A statistical reconstruction of the planet population around Kepler solar-type stars. (2015)

Keywords : astrobiology; methods statistical; planetary systems

Abstract:Using the cumulative catalog of planets detected by the NASA Kepler mission, we reconstruct the intrinsic occurrence of Earth- to Neptune-size (1-4R_{Earth}_) planets and their distributions with radius and orbital period. We analyze 76711 solar-type (0.8<R_*_/R_{sun}_<1.2) stars with 430 planets on 20-200 day orbits, excluding close-in planets that may have been affected by the proximity to the host star. Our analysis considers errors in planet radii and includes an "iterative simulation" technique that does not bin the data. We find a radius distribution that peaks at 2-2.8 Earth radii, with lower numbers of smaller and larger planets. These planets are uniformly distributed with logarithmic period, and the mean number ...(more)

We construct a stellar sample from the Huber et al. (2014, J/ApJS/211/2) catalog of 196468 stars observed during the Kepler mission (Quarters 1-16), selecting "Sun-like" stars with radii 0.8R_{sun}_<R*<1.2R_{sun}_. We restrict the sample to stars with a Kepler magnitude Kp<15.5. Our planet sample is constructed from the 2014 February 26 version of the KOI catalog (Ramirez et al. 2014AAS...22412010R).
