KOI-3158: The oldest known system of terrestrial-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. Whil…
An ancient extrasolar system with five sub-Earth-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
Validation of Twelve Small Kepler Transiting Planets in the Habitable Zone
Guillermo Torres, David M. Kipping, Francois Fressin +23
We present an investigation of twelve candidate transiting planets from Kepler with orbital periods ranging from 34 to 207 days, selected from initial indications that they are sma…
Detection of Stars within 0.8 arcseconds of Kepler Objects of Interest
Rea Kolbl, Geoffrey W. Marcy, Howard Isaacson +1
We present an algorithm to search for the faint spectrum of a second star mixed with the spectrum of a brighter star in high resolution spectra. We model optical stellar spectra as…
Validation of Kepler's Multiple Planet Candidates. II: Refined Statistical Framework and Descriptions of Systems of Special Interest
Jack J. Lissauer, Geoffrey W. Marcy, Stephen T. Bryson +11
We extend the statistical analysis of Lissauer et al. (2012, ApJ 750, 112), which demonstrates that the overwhelming majority of Kepler candidate multiple transiting systems (multi…
Masses, Radii, and Orbits of Small Kepler Planets: The Transition from Gaseous to Rocky Planets
Geoffrey W. Marcy, Howard Isaacson, Andrew W. Howard +100
We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and 7…
Kepler-62: A five-planet system with planets of 1.4 and 1.6 Earth radii in the Habitable Zone
W. J. Borucki, E. Agol, F. Fressin +62
We present the detection of five planets -- Kepler-62b, c, d, e, and f -- of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii, orbiting a K2V star at periods of 5.7, 12.4, 18.2, 12…
A super-Earth-sized planet orbiting in or near the habitable zone around Sun-like star
Thomas Barclay, Christopher J. Burke, Steve B. Howell +28
We present the discovery of a super-earth-sized planet in or near the habitable zone of a sun-like star. The host is Kepler-69, a 13.7 mag G4V-type star. We detect two periodic set…
The Mass of KOI-94d and a Relation for Planet Radius, Mass, and Incident Flux
Lauren M. Weiss, Geoffrey W. Marcy, Jason F. Rowe +15
We measure the mass of a modestly irradiated giant planet, KOI-94d. We wish to determine whether this planet, which is in a 22-day orbit and receives 2700 times as much incident fl…
All Six Planets Known to Orbit Kepler-11 Have Low Densities
Jack J. Lissauer, Daniel Jontof-Hutter, Jason F. Rowe +14
The Kepler-11 planetary system contains six transiting planets ranging in size from 1.8 to 4.2 times the radius of Earth. Five of these planets orbit in a tightly-packed configurat…
