      Crossfield, Ian J M; Ciardi, David R.; Petigura, Erik A.; Sinukoff, Evan; Schlieder, Joshua E.; Howard, Andrew W.; Beichman, Charles A.; Isaacson, Howard; Dressing, Courtney D.; Christiansen, Jessie L.; Fulton, Benjamin J.; Lépine, Sébastien; Weiss, Lauren; Hirsch, Lea; Livingston, John; Baranec, Christoph; Law, Nicholas M.; Riddle, Reed; Ziegler, Carl; Howell, Steve B.; Horch, Elliott; Everett, Mark; Teske, Johanna; Martinez, Arturo O.; Obermeier, Christian; Benneke, Björn; Scott, Nic; Deacon, Niall; Aller, Kimberly M.; Hansen, Brad M S; Mancini, Luigi; Ciceri, Simona; Brahm, Rafael; Jordán, Andrés; Knutson, Heather A.; Henning, Thomas; Bonnefoy, Michaël; Liu, Michael C.; Crepp, Justin R.; Lothringer, Joshua; Hinz, Phil; Bailey, Vanessa; Skemer, Andrew; Defrere, Denis (2016-09-02)
      We present 197 planet candidates discovered using data from the first year of the NASA K2 mission (Campaigns 0-4), along with the results of an intensive program of photometric analyses, stellar spectroscopy, high-resolution ...

    • A nearby m star with three transiting super-earths discovered by k2 

      Crossfield, Ian J M; Petigura, Erik; Schlieder, Joshua E.; Howard, Andrew W.; Fulton, B. J.; Aller, Kimberly M.; Ciardi, David R.; Lépine, Sébastien; Barclay, Thomas; Pater, Imke De; Kleer, Katherine De; Quintana, Elisa V.; Christiansen, Jessie L.; Schlafly, Eddie; Kaltenegger, Lisa; Crepp, Justin R.; Henning, Thomas; Obermeier, Christian; Deacon, Niall; Weiss, Lauren M.; Isaacson, Howard T.; Hansen, Brad M S; Liu, Michael C.; Greene, Tom; Howell, Steve B.; Barman, Travis; Mordasini, Christoph (2015-05-01)
      Small, cool planets represent the typical end-products of planetary formation. Studying the architectures of these systems, measuring planet masses and radii, and observing these planets' atmospheres during transit directly ...

    • Photometrically derived masses and radii of the planet and star in the TrES-2 system 

      Barclay, T.; Huber, D.; Rowe, Jason F.; Quintana, Elisa V.; Christiansen, Jessie L.; Jenkins, J.M.; Mullally, F.; Seader, S.E.; Tenenbaum, P.; Thompson, S.E.; Fortney, J.J.; Morley, C.V.; Fabrycky, D.C.; Barentsen, G.; Bloemen, S.; Demory, B.-O.; Fulton, B.J.; Shporer, A.; Ragozzine, D. (2012-12-10)
      We measure the mass and radius of the star and planet in the TrES-2 system using 2.7 years of observations by the Kepler spacecraft. The light curve shows evidence for ellipsoidal variations and Doppler beaming on a period ...

    • Transit timing observations from Kepler. IV : Confirmation of four multiple-planet systems by simple physical models 

      Fabrycky, Daniel C.; Ford, Eric B.; Steffen, Jason H.; Rowe, Jason F.; Carter, Joshua A.; Moorhead, Althea V.; Batalha, Natalie M.; Borucki, William J.; Bryson, Steve; Buchhave, Lars A.; Christiansen, Jessie L.; Ciardi, David R.; Cochran, William D.; Endl, Michael; Fanelli, Michael N.; Fischer, Debra; Fressin, Francois; Geary, John; Haas, Michael R.; Hall, Jennifer R.; Holman, Matthew J.; Jenkins, Jon M.; Koch, David G.; Latham, David W.; Li, Jie; Lissauer, Jack J.; Lucas, P.W.; Marcy, Geoffrey W.; Mazeh, Tsevi; McCauliff, Sean; Quinn, Samuel; Ragozzine, Darin; Sasselov, Dimitar; Shporer, Avi (2012-05-10)
      Eighty planetary systems of two or more planets are known to orbit stars other than the Sun. For most, the data can be sufficiently explained by non-interacting Keplerian orbits, so the dynamical interactions of these ...
