Two Earth-sized planets orbiting Kepler-20
Francois Fressin, Guillermo Torres, Jason F. Rowe +33
Since the discovery of the first extrasolar giant planets around Sun-like stars, evolving observational capabilities have brought us closer to the detection of true Earth analogues…
Kepler-21b: A 1.6REarth Planet Transiting the Bright Oscillating F Subgiant Star HD 179070
Steve B. Howell, Jason F. Rowe, Stephen T. Bryson +63
We present Kepler observations of the bright (V=8.3), oscillating star HD 179070. The observations show transit-like events which reveal that the star is orbited every 2.8 days by…
Kepler-22b: A 2.4 Earth-radius Planet in the Habitable Zone of a Sun-like Star
William J. Borucki, David G. Koch, Natalie Batalha +80
A search of the time-series photometry from NASA's Kepler spacecraft reveals a transiting planet candidate orbiting the 11th magnitude G5 dwarf KIC 10593626 with a period of 290 da…
Spitzer Infrared Observations and Independent Validation of the Transiting Super-Earth CoRoT-7b
Francois Fressin, Guillermo Torres, Frederic Pont +8
The detection and characterization of the first transiting super-Earth, CoRoT-7 b, has required an unprecedented effort in terms of telescope time and analysis. Although the star d…
Kepler 18-b, c, and d: A System Of Three Planets Confirmed by Transit Timing Variations, Lightcurve Validation, Spitzer Photometry and Radial Velocity Measurements
William D. Cochran, Daniel C. Fabrycky, Guillermo Torres +51
We report the detection of three transiting planets around a Sunlike star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satel…
The Kepler-19 System: A Transiting 2.2 R_Earth Planet and a Second Planet Detected via Transit Timing Variations
Sarah Ballard, Daniel Fabrycky, Francois Fressin +28
We present the discovery of the Kepler-19 planetary system, which we first identified from a 9.3-day periodic transit signal in the Kepler photometry. From high-resolution spectros…
