1 00:00:00,610 --> 00:00:04,430 - [David] All right, nice for having me, I'm trying, 2 00:00:04,430 --> 00:00:07,183 I'm attempting to share my screen. 3 00:00:08,520 --> 00:00:11,730 Do you see my slides fullscreen? 4 00:00:12,860 --> 00:00:14,132 - [Tiffany] Yes, thank you. 5 00:00:14,132 --> 00:00:17,393 - [David] Okay. So it should work then. 6 00:00:18,460 --> 00:00:22,447 So I'm going to talk about CHEOPS. 7 00:00:22,447 --> 00:00:24,310 So CHEOPS stands for 8 00:00:25,190 --> 00:00:28,023 the Characterizing Exoplanet Satellites. 9 00:00:28,980 --> 00:00:33,850 And well here you are seeing obviously an artist impression 10 00:00:33,850 --> 00:00:35,300 of CHEOPS in orbit. 11 00:00:35,300 --> 00:00:39,797 But this is actually the first time I think that anybody 12 00:00:40,880 --> 00:00:44,400 from the Consortium is speaking about CHEOPS 13 00:00:44,400 --> 00:00:46,720 since it's flying. 14 00:00:46,720 --> 00:00:50,510 So I'm really happy to show you what CHEOPS 15 00:00:50,510 --> 00:00:53,820 in the sky actually looks like. 16 00:00:53,820 --> 00:00:57,660 And well, you may not see it very well here 17 00:00:57,660 --> 00:01:02,660 but this photographic trail that you have here is CHEOPS 18 00:01:02,990 --> 00:01:07,940 actually transiting the star of the bright star Eta Aurigae. 19 00:01:07,940 --> 00:01:09,920 So this is taken from Geneva 20 00:01:09,920 --> 00:01:14,440 from a student's 70 centimeter telescope. 21 00:01:14,440 --> 00:01:17,020 So CHEOPS is a real thing now. 22 00:01:17,020 --> 00:01:19,340 And how did we get there? 23 00:01:19,340 --> 00:01:23,040 Well, we had to launch quite obviously. 24 00:01:23,040 --> 00:01:26,303 And this was done at the end of last year. 25 00:01:27,729 --> 00:01:32,729 So CHEOPS was one of the several passenger 26 00:01:33,010 --> 00:01:35,900 in a Soyuz fairing. 27 00:01:35,900 --> 00:01:40,040 So you see here, the frigate module, 28 00:01:40,040 --> 00:01:42,090 before the fairing is closed. 29 00:01:42,090 --> 00:01:47,090 You may see the top of CHEOPS' cover saying hi by the window 30 00:01:49,854 --> 00:01:54,730 and you can also so this is the ferrying closed, 31 00:01:54,730 --> 00:01:58,555 you can guess from the respective sizes of the different 32 00:01:58,555 --> 00:02:02,800 pixels that CHEOS was the prime passenger. 33 00:02:02,800 --> 00:02:07,340 It was actually an Italian defense satellite 34 00:02:07,340 --> 00:02:08,830 was most sky made. 35 00:02:08,830 --> 00:02:12,050 And there were three cube SATs on top of that. 36 00:02:12,050 --> 00:02:15,903 So it was quite a crowded vehicle. 37 00:02:17,460 --> 00:02:22,460 And CHEOS was sitting inside the fagot module. 38 00:02:22,800 --> 00:02:27,290 And it was launched on the 18th of December, '19 39 00:02:27,290 --> 00:02:30,223 from the French Guyana Space Center. 40 00:02:32,160 --> 00:02:34,320 So very nice launch. 41 00:02:34,320 --> 00:02:37,620 And the mission was actually pretty long 42 00:02:37,620 --> 00:02:41,570 because of all the passenger on boats to deploy. 43 00:02:41,570 --> 00:02:46,570 And several hours later CHEOPS successfully inserted 44 00:02:47,356 --> 00:02:51,780 into low Earth orbits at about 700 kilometers, 45 00:02:51,780 --> 00:02:56,320 so higher slightly than Hubble 46 00:02:56,320 --> 00:02:59,880 and it's revolving around the Earth 47 00:02:59,880 --> 00:03:03,120 on Send synchronous orbits so more or less 48 00:03:03,120 --> 00:03:07,960 always on top of the terminator on day 910 gates or looking 49 00:03:07,960 --> 00:03:10,103 at the night side obviously. 50 00:03:12,427 --> 00:03:17,427 So doing so it's join the increasing the growing fleet 51 00:03:18,440 --> 00:03:22,829 of space missions dedicated to exoplanets. 52 00:03:22,829 --> 00:03:27,829 So as a together it became the first small class mission 53 00:03:31,770 --> 00:03:35,747 of ESA, and I believe the first mission of the ESA's 54 00:03:35,747 --> 00:03:40,210 'cause we envision to to actually fly. 55 00:03:40,210 --> 00:03:44,030 And, to my knowledge, it is a global space mission 56 00:03:44,030 --> 00:03:48,210 that is entirely dedicated to study exoplanets 57 00:03:48,210 --> 00:03:50,873 that are already known to exist. 58 00:03:52,220 --> 00:03:57,220 So, S-Class so for small is certainly not sending 59 00:04:00,530 --> 00:04:02,130 a simple the assistance. 60 00:04:02,130 --> 00:04:06,030 because it means that we have a small budgets, 61 00:04:06,030 --> 00:04:09,983 volatility small budget of about ?100 million. 62 00:04:11,930 --> 00:04:14,700 We had to develop in a in a very short time. 63 00:04:14,700 --> 00:04:17,570 And you can see on this table that between 64 00:04:17,570 --> 00:04:21,780 the official adoption of the mission in 2014, 65 00:04:21,780 --> 00:04:25,260 and the delivery of the instruments, 66 00:04:25,260 --> 00:04:27,100 they will just five years, 67 00:04:27,100 --> 00:04:29,220 and we could have launched actually earlier, 68 00:04:29,220 --> 00:04:32,740 but it turns out that there wasn't too many launch 69 00:04:32,740 --> 00:04:35,330 to embark on for the purpose of these. 70 00:04:35,330 --> 00:04:39,800 So we did it in a pretty short time, 71 00:04:39,800 --> 00:04:42,920 and as bona fide European mission, 72 00:04:42,920 --> 00:04:46,150 it involves several countries. 73 00:04:46,150 --> 00:04:51,080 So it's actually a mission between the European Space Agency 74 00:04:51,080 --> 00:04:55,890 and the Consortium, composed by 11 European countries. 75 00:04:55,890 --> 00:05:00,770 So there is something like a 30ish institution, 76 00:05:00,770 --> 00:05:03,350 Although Chris you also Sarah fraction 77 00:05:03,350 --> 00:05:06,210 of the European exoplanet community is already 78 00:05:06,210 --> 00:05:08,290 involved in CHEOPS. 79 00:05:08,290 --> 00:05:10,350 But in spite of all this constraint, of course, 80 00:05:10,350 --> 00:05:12,793 top science is still expected. 81 00:05:13,810 --> 00:05:15,810 So this is the CHEOPS instrument 82 00:05:15,810 --> 00:05:19,077 that was developed by the Consortium, last 2019 83 00:05:20,870 --> 00:05:24,780 and you see, it's to scale here with the PI of the mission 84 00:05:25,650 --> 00:05:27,473 given from the University of Bern. 85 00:05:29,030 --> 00:05:32,030 The instrument itself is a relatively simple. 86 00:05:32,030 --> 00:05:36,630 Which can catch on telescope, with a 30 centimeter mirror 87 00:05:36,630 --> 00:05:40,280 that is capable of intra high-precision photometry. 88 00:05:41,610 --> 00:05:45,880 So the broad question, the big question that CHEOPS 89 00:05:45,880 --> 00:05:50,620 is going to address is what are exoplanets made of? 90 00:05:50,620 --> 00:05:55,520 So in fact, we know that the structure 91 00:05:55,520 --> 00:05:59,900 and the composition of planets is now going much further 92 00:05:59,900 --> 00:06:02,650 beyond what we know in the solar system. 93 00:06:02,650 --> 00:06:06,850 And one key ingredients to constrain the structure 94 00:06:06,850 --> 00:06:10,960 of known exoplanet on their credibiality 95 00:06:10,960 --> 00:06:12,850 is the bulk density. 96 00:06:12,850 --> 00:06:17,850 Now although the bulk density is not sufficient 97 00:06:17,910 --> 00:06:21,030 to determine what's the internal structure of an exoplanet. 98 00:06:21,030 --> 00:06:25,150 However, it's the basic ingredients that you need 99 00:06:25,150 --> 00:06:29,970 to use and for, out of which all the models are built. 100 00:06:29,970 --> 00:06:33,480 So it's really a key quantity to measure 101 00:06:33,480 --> 00:06:34,400 and you do that... 102 00:06:34,400 --> 00:06:37,130 You can do that when you have a precise mass, 103 00:06:37,130 --> 00:06:40,160 and precise size for the planet. 104 00:06:40,160 --> 00:06:43,970 So CHEOPS is about measuring precise sizes 105 00:06:43,970 --> 00:06:46,313 for transiting exoplanets. 106 00:06:47,270 --> 00:06:52,270 And so doing so we will focus on getting precise densities 107 00:06:53,380 --> 00:06:56,200 for Super-earths and neptunes 108 00:06:57,839 --> 00:07:02,060 and doing so we also hope to identify what's golden target 109 00:07:02,060 --> 00:07:05,410 for future atmospheric characterization 110 00:07:05,410 --> 00:07:08,725 with James Webb all with the area, for instance. 111 00:07:08,725 --> 00:07:12,800 So back when the mission was selected in 2012, 112 00:07:12,800 --> 00:07:16,510 it was strategy was fairly simple. 113 00:07:16,510 --> 00:07:20,700 It was half finding trinity of known exoplanets, 114 00:07:20,700 --> 00:07:24,920 and half improving the radii of already known 115 00:07:24,920 --> 00:07:25,963 transiting planets. 116 00:07:27,930 --> 00:07:31,620 And we identified that that we could do was 117 00:07:31,620 --> 00:07:33,320 identify density of planets 118 00:07:33,320 --> 00:07:35,460 and planets detected entirely 119 00:07:35,460 --> 00:07:37,333 by ground-based transit surveys. 120 00:07:38,700 --> 00:07:41,620 So CHEOPS importantly, and that's a big difference 121 00:07:41,620 --> 00:07:44,820 with the TESS or with Kepler, for instance, 122 00:07:44,820 --> 00:07:47,800 it's not a survey, it's a follow of mission. 123 00:07:47,800 --> 00:07:52,800 So it's observed one star at a time, little bit like Hubble, 124 00:07:52,900 --> 00:07:56,290 and as a follow up mission, it must be flexible, 125 00:07:56,290 --> 00:08:00,540 and it better be given how the field evolved, 126 00:08:00,540 --> 00:08:03,220 since the mission was selected in 2012. 127 00:08:06,532 --> 00:08:07,365 In this timeline here, on the top of the screen, 128 00:08:11,160 --> 00:08:13,590 you have all space missions that were known 129 00:08:15,051 --> 00:08:19,680 and planets when CHEOPS was selected back in 2012. 130 00:08:19,680 --> 00:08:23,030 At the bottom, you have got some ground-based instruments, 131 00:08:23,030 --> 00:08:24,130 not exhaustive. 132 00:08:24,130 --> 00:08:27,973 And when CHEOPS launched last year, 133 00:08:29,547 --> 00:08:32,180 the landscape had tremendously evolved 134 00:08:32,180 --> 00:08:35,460 with the continuation of Kepler 135 00:08:35,460 --> 00:08:38,330 to K2 selection, and launch of TESS, 136 00:08:38,330 --> 00:08:43,330 the continuation of Spitzer and so forth and so on. 137 00:08:43,406 --> 00:08:48,406 So, we had to make our science case, evolve accordingly. 138 00:08:49,200 --> 00:08:54,200 And in the past five years, we've come 139 00:08:55,490 --> 00:08:58,370 from this simple picture here, or 140 00:08:58,370 --> 00:09:03,370 something much more diverse in terms of science cases, 141 00:09:03,960 --> 00:09:06,270 and I'm not going to go through all of them. 142 00:09:06,270 --> 00:09:10,620 I'm just going to highlight one that may seem surprising 143 00:09:10,620 --> 00:09:13,970 for a photometric mission like CHEOPS 144 00:09:13,970 --> 00:09:16,920 is the characterization of things of planetary atmospheres. 145 00:09:17,980 --> 00:09:22,980 In fact, just with optical photometry 146 00:09:23,000 --> 00:09:25,010 we should be able to determine 147 00:09:25,010 --> 00:09:28,580 how common are very reflective hot Jupiters, 148 00:09:28,580 --> 00:09:30,713 likes of Kepler-7 for instance. 149 00:09:32,460 --> 00:09:35,680 And burning question right now is about 150 00:09:35,680 --> 00:09:39,870 the ultrahot gas giants that are extremely close 151 00:09:39,870 --> 00:09:44,870 to very hot stars and how reflective these planets are. 152 00:09:45,810 --> 00:09:49,750 And you may have seen that this is not a fiction 153 00:09:49,750 --> 00:09:54,520 because already TESS is obtaining gorgeous results 154 00:09:54,520 --> 00:09:58,220 by observing not only the transits, 155 00:09:58,220 --> 00:10:00,430 but also the occultation, 156 00:10:00,430 --> 00:10:02,730 if you can see my mouse cursor here, 157 00:10:02,730 --> 00:10:05,800 the occultation and the face curve 158 00:10:05,800 --> 00:10:09,600 of some of these extremely hot exoplanets, 159 00:10:09,600 --> 00:10:14,600 which are revealing the most extreme climates 160 00:10:15,970 --> 00:10:20,383 in the Universe that you can find on an exoplanet. 161 00:10:21,440 --> 00:10:24,351 So, we will be able to do these kinds of science 162 00:10:24,351 --> 00:10:26,113 with CHEOPS as well. 163 00:10:28,110 --> 00:10:29,010 So this... 164 00:10:31,060 --> 00:10:33,990 Now the guarantee time of servation program 165 00:10:33,990 --> 00:10:38,810 comprises over 30 different science programs, 166 00:10:38,810 --> 00:10:42,090 over several hundreds of targets 167 00:10:42,090 --> 00:10:45,043 between 300 and 400 at present. 168 00:10:46,840 --> 00:10:50,707 The primary mission is supposed to last for 169 00:10:50,707 --> 00:10:53,960 three and a half year, and right know the GTO program 170 00:10:53,960 --> 00:10:57,070 can feel two and a half year there. 171 00:10:57,070 --> 00:11:01,200 I will mention right away that's 20% of CHEOPS time 172 00:11:01,200 --> 00:11:02,810 is open to the community. 173 00:11:02,810 --> 00:11:05,550 So, you will be able to apply, 174 00:11:05,550 --> 00:11:07,730 some of you may have already obtained 175 00:11:07,730 --> 00:11:12,373 some time on CHEOPS this will be renewed every year. 176 00:11:14,140 --> 00:11:18,200 And the big challenge once we have this program 177 00:11:18,200 --> 00:11:22,840 we have all these time critical observation of exoplanets 178 00:11:22,840 --> 00:11:27,840 to observe, combined with the observational constraints 179 00:11:28,000 --> 00:11:31,410 that we get from being in low Earth orbits. 180 00:11:31,410 --> 00:11:33,680 We are also going to also potations 181 00:11:33,680 --> 00:11:36,920 South Atlantic anomaly, which we are familiar with Hubble 182 00:11:36,920 --> 00:11:39,970 observations sound this will ring a bell. 183 00:11:39,970 --> 00:11:43,480 Well, here the difference is that all our observation, 184 00:11:43,480 --> 00:11:45,240 note all of them are time critical. 185 00:11:45,240 --> 00:11:49,580 So we needed to implement quite a mission planning system 186 00:11:49,580 --> 00:11:54,380 that would operate about autonomously 187 00:11:54,380 --> 00:11:58,980 because as I will show you, you have very limited resources 188 00:11:58,980 --> 00:12:00,480 for operating satellite, 189 00:12:00,480 --> 00:12:03,333 that's one of the thing of being a small mission. 190 00:12:04,420 --> 00:12:09,250 So we implemented an automatized planning software 191 00:12:09,250 --> 00:12:14,000 optimized to trying to optimize the observational efficiency 192 00:12:14,000 --> 00:12:15,830 based on generic algorithm. 193 00:12:15,830 --> 00:12:20,830 This actually proved a very important thing to have, 194 00:12:20,970 --> 00:12:22,670 because that's made the mission 195 00:12:22,670 --> 00:12:24,160 at the end of its commissioning 196 00:12:24,160 --> 00:12:26,400 and the start of routine operations, 197 00:12:26,400 --> 00:12:31,400 basically, resistance to the critical COVID-19 situation, 198 00:12:31,620 --> 00:12:34,920 and we could continue to operate the satellite 199 00:12:35,980 --> 00:12:39,460 at this very critical phase of its existence, 200 00:12:39,460 --> 00:12:43,467 due to the capability of the science operations 201 00:12:45,770 --> 00:12:48,660 and try to operate like remotely 202 00:12:48,660 --> 00:12:53,660 and and with very light touch intervention from people. 203 00:12:54,630 --> 00:12:58,860 With immediate obviously, but that's really was a big help 204 00:13:01,270 --> 00:13:04,083 to cross this difficult time. 205 00:13:05,591 --> 00:13:06,424 In fact- 206 00:13:06,424 --> 00:13:09,663 - [Tiffany] David Sorry, just to interrupt that. 207 00:13:09,663 --> 00:13:11,070 You're at the roughly 12 minute mark, 208 00:13:11,070 --> 00:13:11,950 just to give you a heads up. 209 00:13:11,950 --> 00:13:13,983 - [David] Great, thank you Tiffany. 210 00:13:13,983 --> 00:13:17,930 So infact with contrast with all previous ESA mission, 211 00:13:17,930 --> 00:13:20,070 there's science operation center 212 00:13:20,070 --> 00:13:24,290 not at the big center in Darmstadt in Germany. 213 00:13:24,290 --> 00:13:26,040 It's in a small office 214 00:13:26,040 --> 00:13:29,303 at the University of Geneva observatory. 215 00:13:30,400 --> 00:13:33,800 The antenna that you see here is actually a water heater, 216 00:13:33,800 --> 00:13:36,693 it's a fake antennas, so the real antenna is in Spain. 217 00:13:37,960 --> 00:13:42,960 But this is the real science operation center. 218 00:13:44,440 --> 00:13:46,600 So you can see it's not not a lot of people. 219 00:13:46,600 --> 00:13:48,060 One of them actually retired, 220 00:13:48,060 --> 00:13:51,930 so you can imagine that it's not a lot 221 00:13:51,930 --> 00:13:56,687 and we have to rely a lot on automatic operation. 222 00:13:58,030 --> 00:14:01,020 Nonetheless, they are doing it tremendous job 223 00:14:01,020 --> 00:14:04,193 in planning the mission, it's working very well. 224 00:14:05,981 --> 00:14:10,830 So this slide is showing a simulation. 225 00:14:10,830 --> 00:14:15,010 This is the acoustic plan that you've just seen, 226 00:14:15,010 --> 00:14:18,763 it's showing on this, these are the poles. 227 00:14:21,890 --> 00:14:24,620 What I'm going to show you here is the overlap 228 00:14:25,470 --> 00:14:29,840 between the visible sky of CHEOPS. 229 00:14:29,840 --> 00:14:32,550 And here the visible sky of TESS 230 00:14:32,550 --> 00:14:35,600 with obviously better at the equity polls 231 00:14:35,600 --> 00:14:37,800 where as we can't go and you can suppose 232 00:14:37,800 --> 00:14:42,215 but on all the parts of the sky, we can follow up 233 00:14:42,215 --> 00:14:43,623 TESS objects. 234 00:14:44,580 --> 00:14:47,860 And so there are several hundreds of this objects 235 00:14:47,860 --> 00:14:50,110 that we can that you can follow up, 236 00:14:50,110 --> 00:14:52,130 but not that they're critical. 237 00:14:53,030 --> 00:14:57,100 Another consequence of our visibility zone, 238 00:14:57,100 --> 00:14:59,770 and that's the Kepler field of view is 239 00:15:01,360 --> 00:15:02,653 Basically out of view. 240 00:15:03,720 --> 00:15:07,480 On the other hand the K2 pointings on the acoustics 241 00:15:07,480 --> 00:15:10,847 are perfect, this is where we are good at 242 00:15:10,847 --> 00:15:13,693 and we can follow up many of these systems as well. 243 00:15:17,090 --> 00:15:21,260 Alright, so now to finish I'd like to give you what happens 244 00:15:21,260 --> 00:15:25,603 since the launch, since December 2019. 245 00:15:26,940 --> 00:15:31,230 So basically the first thing we did was did nothing. 246 00:15:31,230 --> 00:15:34,390 We had the mission steep over Christmas, 247 00:15:34,390 --> 00:15:39,100 and we switched it on the beginning of January 2020. 248 00:15:40,260 --> 00:15:44,390 And I believe I've never been more happy 249 00:15:44,390 --> 00:15:47,290 to see a darker image. 250 00:15:47,290 --> 00:15:49,311 These are the Phils darks that were obtained 251 00:15:49,311 --> 00:15:54,311 with the satellites with the cover closed. 252 00:15:54,419 --> 00:15:55,270 (coughs) 253 00:15:55,270 --> 00:15:56,370 Sorry. 254 00:15:56,370 --> 00:16:00,510 And at the end of January, we actually did 255 00:16:00,510 --> 00:16:03,100 this very critical one shot variation 256 00:16:03,100 --> 00:16:05,020 to open the cover. 257 00:16:05,020 --> 00:16:08,540 It worked, and we could obtain our first image, 258 00:16:08,540 --> 00:16:12,750 so you see here a stellar field and the zoom 259 00:16:12,750 --> 00:16:16,010 on the targets star, zoom on the PSS. 260 00:16:16,010 --> 00:16:19,420 And if you're used to seeing stellar PSF 261 00:16:19,420 --> 00:16:23,270 this one might look like a little bit weird. 262 00:16:23,270 --> 00:16:27,010 But actually it's better than we expected. 263 00:16:27,010 --> 00:16:32,010 And although it has a weird triangular shape 264 00:16:33,500 --> 00:16:37,070 so it's predit out of focus on purpose, 265 00:16:37,070 --> 00:16:39,910 it's spread of on hundreds of pixel 266 00:16:39,910 --> 00:16:42,023 to increase the photometric accuracy. 267 00:16:43,023 --> 00:16:46,860 And it's less peaky and larger 268 00:16:46,860 --> 00:16:51,770 that was predicted from simulation. 269 00:16:51,770 --> 00:16:53,220 And this is a very good news 270 00:16:53,220 --> 00:16:56,773 for the photometric accuracy on bright stars. 271 00:16:57,940 --> 00:17:01,330 After a lot of work by wonderful dedicated team, 272 00:17:01,330 --> 00:17:05,852 we successfully passed the in-orbit commissioning review 273 00:17:05,852 --> 00:17:09,240 at the end of March, so a few months ago. 274 00:17:09,240 --> 00:17:14,240 And we could compare the actual performance in-flight 275 00:17:15,020 --> 00:17:16,710 with the pre-flight performances 276 00:17:16,710 --> 00:17:20,110 which were established from a combination 277 00:17:20,110 --> 00:17:24,160 of calibration at the lab. 278 00:17:24,160 --> 00:17:28,490 We had to invent a source of flight stable enough 279 00:17:28,490 --> 00:17:30,690 so that we could actually test 280 00:17:30,690 --> 00:17:32,420 the stability of the instruments 281 00:17:32,420 --> 00:17:35,293 because nothing existing previously. 282 00:17:36,700 --> 00:17:40,257 You can take these papers if you're interested by that. 283 00:17:40,257 --> 00:17:41,800 That's already published. 284 00:17:41,800 --> 00:17:43,660 We need a lot of simulations as well 285 00:17:43,660 --> 00:17:47,363 And weare describing the data diction photometric pipeline. 286 00:17:48,320 --> 00:17:51,780 And I would like to spend like the last one minutes 287 00:17:51,780 --> 00:17:55,270 to tell you about the east light performances. 288 00:17:55,270 --> 00:18:00,270 So the first thing we did was to obtain a long flat sequence 289 00:18:00,460 --> 00:18:02,890 photometry on the quiet star. 290 00:18:02,890 --> 00:18:06,940 So, here you see a real images taken by CHEOPS 291 00:18:06,940 --> 00:18:10,260 and although it looks quite messy with rotating fields 292 00:18:10,260 --> 00:18:15,260 and quite challenging, we still achieve very good accuracy. 293 00:18:15,390 --> 00:18:17,210 So this is a photometric time series 294 00:18:18,140 --> 00:18:21,180 that allow to check the requirements on bright stars. 295 00:18:21,180 --> 00:18:25,540 And we found that we use a metric that is similar 296 00:18:25,540 --> 00:18:30,340 to Kepler's CDPP and in short, 297 00:18:30,340 --> 00:18:33,000 it's sliding lean over six hours. 298 00:18:33,000 --> 00:18:37,270 And when we apply it to the time series 299 00:18:37,270 --> 00:18:42,270 we obtained photometric precision of 11.2 parts per million, 300 00:18:44,020 --> 00:18:46,530 whereas our required photometry requirements 301 00:18:46,530 --> 00:18:49,210 for this kind of star was 20 ppm. 302 00:18:49,210 --> 00:18:53,700 So for bright stars, we are better than the requirement. 303 00:18:53,700 --> 00:18:57,780 And here is a thin star so at the paint end 304 00:18:57,780 --> 00:18:59,639 we've magnitude 12 305 00:18:59,639 --> 00:19:04,430 and We've photometric requirement was 85 ppm in three hours 306 00:19:04,430 --> 00:19:06,220 and we are around the requirements, 307 00:19:06,220 --> 00:19:07,883 slightly better in this case. 308 00:19:09,030 --> 00:19:11,187 But we are we are basically 309 00:19:12,821 --> 00:19:15,463 good to go for even for things for faint stars. 310 00:19:16,800 --> 00:19:21,800 So let me end by a at last showing you our first transit 311 00:19:22,970 --> 00:19:24,870 that we obtained during commissioning. 312 00:19:26,232 --> 00:19:31,232 KAELT-11b is very interesting transiting exoplanets 313 00:19:31,440 --> 00:19:36,440 because it is transiting a very bright big sub-giants 314 00:19:37,340 --> 00:19:39,790 that you see here to scale with the sun. 315 00:19:39,790 --> 00:19:42,900 And the 9th of March, it was a very long transit 316 00:19:42,900 --> 00:19:44,670 because the star is bright 317 00:19:44,670 --> 00:19:47,558 so it's difficult to observe from the ground. 318 00:19:47,558 --> 00:19:48,880 And then the 9th of March, 319 00:19:48,880 --> 00:19:51,470 we attempted filtered it observation, 320 00:19:51,470 --> 00:19:53,030 which is always a magical moment 321 00:19:53,030 --> 00:19:57,260 because it's already kind of magic that you can predict 322 00:19:57,260 --> 00:19:59,367 when the planet is going to be in front of the star, 323 00:19:59,367 --> 00:20:03,530 also that we routine by now I'm still always freaked out 324 00:20:03,530 --> 00:20:06,840 when it comes to check whether it worked 325 00:20:06,840 --> 00:20:11,000 and it worked really nicely. 326 00:20:11,000 --> 00:20:15,450 And you see here the first KELT from the fly job 327 00:20:15,450 --> 00:20:17,400 with the residual in the bottom. 328 00:20:17,400 --> 00:20:21,650 So the radius ratio between the planets on the star 329 00:20:21,650 --> 00:20:25,810 as a precision of better than 1% here 330 00:20:25,810 --> 00:20:28,690 and you can see that you have the physical measurement 331 00:20:28,690 --> 00:20:31,200 of the of the size of the planet, 332 00:20:31,200 --> 00:20:35,567 which is 19,500 kilometers plus or minus 333 00:20:35,567 --> 00:20:39,500 a little bit less than 2000 kilometres. 334 00:20:39,500 --> 00:20:41,790 Let me show you that graphically, 335 00:20:41,790 --> 00:20:46,407 that basically the width of the blue circle here 336 00:20:49,990 --> 00:20:53,410 and I am just going before stopping 337 00:20:53,410 --> 00:20:56,130 I just need to recall what I said 338 00:20:56,130 --> 00:20:59,050 that there is a Guest Observer program 339 00:20:59,050 --> 00:21:04,050 that was on 20% observing time to the whole community. 340 00:21:05,570 --> 00:21:07,240 Don't need to be easy to apply 341 00:21:07,240 --> 00:21:09,120 you can be on any science topic 342 00:21:09,120 --> 00:21:11,400 using the capabilities of CHEOPS. 343 00:21:11,400 --> 00:21:16,400 The second goal for opportunity will be issued by ESA 344 00:21:16,700 --> 00:21:21,700 and dealt with by ESA during the fall 2020. 345 00:21:21,720 --> 00:21:25,800 And ESA is also preparing the opening 346 00:21:25,800 --> 00:21:30,800 of Director of Discretionary Time program very soon. 347 00:21:30,990 --> 00:21:32,730 So I thank you for attention. 348 00:21:32,730 --> 00:21:34,463 I'm sorry, I was a bit long. 349 00:21:35,930 --> 00:21:37,620 But if you have questions nonetheless, 350 00:21:37,620 --> 00:21:38,850 do not... 351 00:21:38,850 --> 00:21:40,187 Happy to take them.
