Chas Beichman for Jessie Christiansen
NASA Exoplanet Science Institute (NExScI), NASA Exoplanet Archive Update

So our next speaker is Chas Beichman.
And it will give us an update about NExScI and NASA exoplanet archive.
Thank you. As you may have noticed, I'm not Jessie Christiansen.
This is a serious downgrade.
I apologize. Jessie's evacuated her.
She's fine.
Her family's fine.
Her house is fine, but she figured best to stay home.
So here we are.
So I'm director of the Exoplanet Science Institute.
Jessie is the chief scientist.
Dave Ciardi is the deputy.
He also has family.
Or in the evacuation warning zone and.
He'll be giving a talk tomorrow, either in person or I'll give it form, in which case that's an upgrade. If you if I give the talk forum, we'll see how it, how it plays out. OK. So I'll just give you a quick set of slides about next slide.
Next slide please, Jennifer.
Do I press the button here and it'll all just work?
Well, OK, so we're ExEP Science Center, we serve the exoplanet community is a focused Science Center for the program.
We're located on the Caltech campus as part of IPAC. We support a broad range of.
Science efforts using NASAs and other facilities with telescope access, data archives, analysis tools and play a key role in community training through the Sagan program.
For example.
This week is the reviews for the NASA Hubble Fellowship program next week.
That Dawn also runs among the fifty other things that she runs that chooses the Sagan fellows as part of the Nhfp and also the summer workshop which I'll describe.
On the next slide.
I'm gonna break it.
I know I am. Oh, good.
So it is hard to imagine, but the next summer workshop is our 25 years.
Silver Jubilee Workshop and it's on the topic is exoplanet demographics, and we're going to focus on how each of the individual techniques on which we've given, you know, workshops in the past from RV and transits to imaging, astronomy and microlensing all contribute to our understanding of demographics of.
Exoplanet systems.
If you think about the image of the blind people feeling the elephant.
This is where we are with all the different techniques we're trying to understand the demographics of exoplanet systems and we'll try and put it together so it'll be upcoming July. Fully hybrid, we expect 200 plus people in person and many more online.
We're typically up to 750 to 1000 participants hands on data, software exercises, poster activities and so on.
Registrational open shortly and they'll be travel support available for early career scientists.
With applications due by mid March.
It's really AI think going to be really a terrific meeting, listed the Science organizing committee there, Alan Boss and Courtney dressing and a host of experts in all the different fields.
So we certainly hope you'll consider coming.
So community observing resources.
Don alluded to this.
Next slide is responsible for the administration of the roughly 90 nights a year 16 partnership with the Keck Observatory. So it supports strategic programs from all of astrophysics, not just exoplanets.
But it's all astrophysics and solar system science.
All instruments, both telescopes.
So.
I'll have another slide on that in a moment.
Dawn mentioned also the NN Explorer program which has roughly 40% of the time on the wind telescope, which includes both the new and PRV instruments. Had benders here. If you want to get more details on that.
Also, there's a direct imaging instrument both on the wind telescope and on the two Gemini telescopes.
There's also southern PRV opportunities.
Smarts Chiron, which is I think coming back online after.
You know, renter landlord, disputes with noir labs.
You can ask Steve Ridgeway about those.
And there's more information that'll be available at the at the I PAC booth.
A bit more on NASA Keck Time 25B proposals are due of March 13th.
The oversubscription rate is about 5 to one, a little bit more depends on the on the telescope. There are currently 5 Keck Strategic Mission support programs selected running through the end of.
25B may be dribbling into 26 a.
There'll be another round of ksms opportunities either IN26A or 26B.
The Keck Planet Finder, which is the new.
Extreme precision radio velocity machine on Keck is now available for community proposals.
All the proposals are dapper compliant and.
We also make available through JWST.
Joint observations between KEK and JWST, with the time going only through the JWST time allocation.
Committee. So if you have AJW proposal that needs Keck time, you just apply for it once and they have a pool of keg time that they can that they can allocate. And typically it's two or three nights per semester depending just given the oversubscription rate on on J.
In addition to the data that are available through NASA time, we also run it.
Next slide, the Keck Observatory Archive and that has every bit from every instrument.
That's ever been obtained by all partners on the telescope goes through the archive and.
You can basically now ingest all the data in real time, typically under a minute after the data are created, it winds up in the in the archive the archive started out as just getting data from the high res instruments for PRB.
We just sort of went along and started archiving every all the other instruments and didn't ask anybody and we're continuing to do that and now it's really a great resource and approximately 15 to 20% of all the papers coming out of the Keck Observatory now are based.
On data.
Least taken in part from the archives.
So I think that's really been a great success.
There is a 12 month proprietary period.
And we notify people of that.
A few.
A few weeks or a month before their data go public and you can ask for extensions either when you propose or up through the moment your data go public.
And those are granted occasionally based on criteria that we.
We post on the website, but it's basically my grad student is just finishing up.
He really needs the data for his thesis.
Yeah, my cat ate my homework is not typically a valid excuse.
But we'll certainly entertain them all. And we're, you know, continually updating the archive and making it more performant. And, you know, API accessible as well.
Thing you probably you know used at nexai is the Exoplanet Archive, which is really NASA's repository for all the information on exoplanets. That makes it through into the referee literature.
This is really Jesse's.
Dave Ciardi's.
Work with the whole team at NExScI. We've just added a couple of 100 new planets recently.
Lots of new parameter data sets. New all the atmospheric Spectra that have been taken with Hubble's or Spitzer, and now JWST are available in there for. These are the Level 3 products, not the lower level products that are available at master, the Spitzer Archive, so we're continu.
To add data wherever we can and try to integrate it for people to analyse.
Contributed data sets.
We have small set data sets acute the ultra Wide Transit experiment is.
Coming, we're also putting in a catalog for the HWO input catalog so people can start looking at that.
There's an atmosphere environment where you can over plot all the different Spectra, either direct imaging or or the transit data.
And again, a lot of this is all available through API access.
So you can, you know, do it all through your Python code.
The Exo FOP is the other service that we offer, and this is really the sandbox for. If you have data.
Supporting Kepler K2 tests, you want to upload data.
An RV image or if you want to see if someone has taken image or do you need to get one.
Is there a spectrum that's needed or properties of the star you can find out if you need to take it, or if you just need the data, you can go there and get information on the stars. The planets we've added.
Now an EXO FOB portal for Hwo target so people can start adding in data for those.
Stars as we start building towards hwo precursor.
And preparatory science, and also as Dave Ciarti, will discuss tomorrow on the aerial mission, and Giovanna is here to talk about that tomorrow as well, which will be a transit characterization project to study between 500 and 1000 exoplanets in a very uniform way. Those targets coming.
From Tess or Kepler need a lot of characterization. They'll be programs.
As John discussed to to support that.
So we're starting to build up the website to make.
Those data available for the community to work with, and I think that's it.
Thank you very much.
Any question let me make an informal suggestion so.
On the NASA X Plant Archive, I think it would be very helpful to have stellar properties now.
There are many works that have done homogeneous stellar characterization using Gaia, for instance, and so it would be good to ingest some of those information there as well, and in some sense those are already there. I mean, if you go to the archive page for your favorite T.
Object.
There is definitely information on stellar properties.
But it's not homogeneous, right?
Now, if the world had there's homogeneity and there's homogeneity, I mean, where do you get the abundances? You know, obviously DR3 and DR4 make great advances for that. And we're debating now how to really, we skipped over DR3.
We're really planning a major integration of Dr. 4.
But you know, there's still gonna be a very heterogeneous data set, cause some stars, particularly the brighter ones at hwo cares about, are not well characterized by Gaia. And you know abundances come from somewhere else.
So stars are just a mess.
And planets are not because we don't know them well.
But yeah, no, you're much well taken, I know.
Thanks. Any other quick question before the break.
OK, I want to make a quick announcement, which is really great news.
Jonathan, thank you very much.
So Jonathan Lunin, chief scientist from JPL, has agreed to provide coffee to you guys.
So we will have coffee.
Thank you, Jonathan.
