  1. How Sagan Fellows are shaping the success of NASA’s K2

    Mission Geert Barentsen K2 GO Director 2017 Nov 9
  2. Sagan Fellow Sagan Fellow Sagan Fellow Sagan Fellow For K2

    to be funded, science had to be demonstrated
  3. K2’s open data is empowering talent across institutions Crosses show

    the institutions of K2 paper authors and co-authors.
  4. K2’s open data is empowering citizen scientists A K2 citizen

    science project led by Ian Crossfield
 and Jessie Christiansen featured on prime-time TV in Australia this year (1 million viewers)

    (2017) Sagan Fellow Sagan Fellow K2 discoveries, all from
 the past 14 months
  11. 99 Kepler/K2 papers have a Sagan Fellow as first author.

    These papers have been cited 3943 times.
  12. K2’s archived data set size just increased by 50% K2

    has now surpassed the number of unique targets
 that were observed during Kepler’s prime mission
  13. K2’s Campaigns 16 & 17 will enable new science The

    community has secured
 >24 ground-based facilities
 to support the forward-facing Campaigns 16 & 17: • Enables spectroscopic characterization of supernovae. • Enables simultaneous measurements of RV jitter and photometric stability to Kepler precision. • Observe dozens of unconfirmed Earth-sized planet candidates seen in previous Campaigns.
  14. Campaign 18 revisits K2’s legacy field Campaign 18 will revisit

    the key part of the sky that includes benchmark solar-like (M67) and young (M44) star clusters. This is K2’s legacy field; it will benefit from a 3-year baseline and 8-month duty cycle. Enables prime-mission-like science at a different Galactic sight line from the original mission: • Exoplanet TTVs; • Long-term stellar activity; • Asteroseismology.
  15. Proposal opportunities DDT deadlines for exceptional targets: C17: Nov 30,

    2017 (any new planets from C6?) C18: Jan 19, 2018 (any new planets from C5?) C19: Apr 12, 2018 (any new planets from C12?) K2 Cycle 6 Phase-2 deadline for funding (~$20-$150k grants): Apr 19, 2018
 Proposals may only use C17-18-19 targets selected in Phase-1 (target lists to be published in February). See ROSES D.7 for details. Also: propose to ADAP and XRP!
  16. Dr Ann Marie Cody Crowded field photometry support High Level

    Science Product manager Workshop organizer Zé Vinícius (intern) PyKE community tools PSF photometry expert Probabilistic inference Dr Michael Gully-Santiago
 Supernova experiment support Low-fuel science simulations Systematics removal tutorials Dr Christina Hedges Science tutorials Solar System light curves Chromatic abberation expert We can help! Introducing the new K2 GO team:
  17. from pyke import KeplerTargetPixelFile tpf = KeplerTargetPixelFile(“file.fits”) tpf.show_movie() lightcurve =

    tpf.to_lightcurve().detrend(method=“sff”) lightcurve.fold(phase=274.1, period=31.4).plot() PyKE is turning into an AstroPy-quality library for building your custom pipelines and tools
  18. Visit the K2 team at NASA Ames; we have visitor

    desks and coffee! Sagan Fellow
