Issue 8 - October 2012
Over the summer, changes have been underway within the Exoplanet Program and throughout NASA's Astrophysics division. Shortly after the last Newsletter appeared, Mike Devirian retired as ExEP Program Manager. At the time of writing, the prospective candidates for Mike's position are being interviewed, and you can look forward to a permanent replacement being announced in the very near future. At NASA HQ there are changes as well... Read More
Sadly, we start our update this quarter with the news that David Koch, Deputy PI for Kepler, passed away on 12 September, from complications of ALS, Lou Gehrig's disease, at his home in Milwaukee. Many of the qualities that make the Kepler mission such a success are due to Dave's foresight and diligence. We send our sincere condolences to his family and friends - he will be missed.
Turning to future mission planning, the excitement over the 2.4-m telescopes recently donated to NASA was made evident at a 3-day meeting at Princeton University, hosted by David Spergel, devoted to an 2.4-m WFIRST configuration, including a coronagraph option (as requested by NASA HQ).

As Kepler begins it extended mission on 1 October 2012, the rate of public data release will ramp up. On 28 July, Kepler released quarter 7 thru quarter 9 data to the MAST archives. On 28 Oct 2012, the final proprietary exoplanet survey data will be released to the public. Subsequently all exoplanet survey data will be released to the public immediately upon completion of pipeline processing and verification. Science data for quarter 13 has been downloaded and processing of quarter 13 will commence in September. Read More...
4. Monsoon Clears, LBTI NearsBy Rafael Millan-Gabet
As the Arizona Monsoon season ends, the Large Binocular Telescope (LBTI, Principal Investigator Phil Hinz - University of Arizona) gets ready to resume commissioning activities and, in parallel, start shared risk exozodi key science. The next two observing runs are scheduled for late September and late October. Over the Summer shutdown, the team worked hard on instrument improvements and testing, both hardware and software. Most notably, the near-infrared phase sensor system was tested and is ready to be used on the sky. In late July, a "proof-of-concept" version of the LBTI archive at NExScI was delivered. In mid-September, the LBTI project held an instrument status review, as well as the first meeting of the newly selected exozodi key science team.
5. First WFIRST Study in Bag, Time to Tackle TelescopeBy Steve Howell and Neil Gehrels
Hurray! The 2-year study of WFIRST is complete. It was presented to NASA HQ this summer and is now posted on astro-ph. The study was performed by the Project Offices at Goddard and JPL and the community Science Definition Team (http://wfirst.gsfc.nasa.gov/). It includes two concepts call Design Reference Mission (DRM)1 and DRM2, with DRM1 more capable and DRM2 lower cost and not duplicating capabilities of Euclid, LSST and JWST. DRM1 meets all of the requirements dictated by the Decadal Survey for WFIRST in its 5-year mission. DRM2 meets a subset of requirements in its 3-year mission, but could cover all of them in an extended operations phase.
The next step for WFIRST will be to study a version of the mission utilizing one of two 2.4m telescopes recently donated to NASA. A NASA HQ call is going out to form a new SDT for this rapid 6-month study.
6. No Trouble with the Curve: 173 Attend Sagan ConfabBy Dawn Gelino
NExScI hosted the very successful 2012 Sagan Summer Workshop, "Working with Exoplanet Light Curves", July 22-27 on the Caltech campus. There were 173 registrants in attendance from 26 different countries for this, the 14th and by far the largest of, the Sagan/Michelson Workshops. In addition to several interactive workshop features, NExScI ran several hands-on sessions dealing with public Kepler data using the Amazon Web Cloud Computing Services. This is the first time that the Amazon Cloud has ever been used in this capacity, so it marks a very big achievement for NExScI as well as for cloud computing! Written feedback from about 100 of the workshop attendees and speakers was universally positive. Video and audio recordings of the presentations will be available soon; in the meantime, slides from the invited and contributed presentations, as well as contributed electronic posters, are currently available from the workshop website: http://nexsci.caltech.edu/workshop/2012.
7. Sagan Fellows Dish on Exoplanet ResearchBy Carolyn Brinkworth
Every issue, we run updates from a couple of our current Sagan Fellows (see below for highlights from David Kipping and Bryce Croll). If you like what you've been reading and want to know more, we have a great opportunity for you! The Sagan/Michelson Fellows Symposium will be held at Caltech on November 8-9th, featuring talks from current and past Sagan and Michelson Fellows, highlighting their cutting-edge exoplanet research. Registration is now open at the symposium website linked above, and is free to all. If you have any questions, please email the NExScI team at firstname.lastname@example.org
8. Kepler Bearing down on Elusive ExoMoonsBy David Kipping
It seems every week we hear about the amazing Kepler Mission detecting another incredible first, be it a sub-Earth sized planet, or a circumbinary world or even recently a disintegrating gas giant. One of the big "firsts" still evading us is an exomoon, which is what I spend my Sagan fellowship working on. In my first year as a Sagan fellow I've been working hard at setting up the "Hunt for Exomoons with Kepler" project (www.cfa.harvard.edu/HEK/). See http://arxiv.org/abs/1208.0942 for our recent Science paper on a detection of the first non-transiting planet via transit timing variations (sadly not a moon!). We're looking forward to sharing more exciting systems soon, so stayed tuned.
9. Chasing Exo Spectra from the GroundBy Bryce Croll
Much of the press and the intrigue arising from exoplanet research in the past few years has involved the quest to discover and characterize ever smaller exoplanets, ever closer to smack dab in the middle of the habitable zone. However, even once we've discovered one of these worlds, it is largely an unanswered question whether astronomers will be able to achieve the photometric precision required to detect or rule out biomarkers and signs of life in its atmosphere. Although space telescopes will be undeniably crucial to characterizing the atmospheres of these planets, it will arguably always be cheaper and quicker to utilize telescopes on the ground - if, that is we are able to overcome the systematic errors limiting our precision that often frustrates work from the ground. My research involves achieving precise near-infrared observations from the ground in the near-infrared to characterize the atmospheres of larger exoplanets -- everything from the thermal emission of massive hot Jupiters (see here and here), to the spectra and thus the kind of atmosphere enveloping a small, super-Earth -- and thereby developing the techniques that may be applicable to searching for biomarkers in the atmospheres of pale, blue dots other than our own.
10. New 3D Viz Tool Coming to a Computer Near YouBy Randal Jackson
The Exoplanet Exploration Program outreach team has spent this past summer developing "Eyes on Exoplanets," a 3D visualization tool for exploring all 809 exoplanets so far discovered. Based on the Unity3D game engine, this visually stunning database is searchable and continually updated and includes interactive 3D models of every exoplanetary system and host star, along with distance scales, habitable zone overlays, and tools for comparisons with our own solar system. There's also a search engine, and the data pipeline is delivered through NASA's own Exoplanet Archive. "Eyes on Exoplanets" is currently in beta testing phase, and will be available to the public, educators and scientists this fall through the PlanetQuest website (no plugin required!).
