Joshua N. Winn,Robert W. Noyes,Matthew J. Holman,David Charbonneau,Yasuhiro Ohta,Atsushi Taruya,Yasushi Suto,Norio Narita,Edwin L. Turner,Edwin L. Turner,John Asher Johnson,Geoffrey W. Marcy,R. Paul Butler,Steven S. Vogt +13 more
TL;DR: In this paper, the Rossiter-McLaughlin effect was used to determine the inclination of the planetary orbit relative to the apparent stellar equator and the line-of-sight rotation speed of the star.
Journal ArticleDOI
The Mass-Radius Relation for 65 Exoplanets Smaller than 4 Earth Radii
TL;DR: In this article, the masses and radii of 65 exoplanets smaller than 4 Earth radii with orbital periods shorter than 100 days were studied and a density maximum of 7.6 g/cc was identified.
Journal ArticleDOI
The Lick Planet Search: Detectability and Mass Thresholds
TL;DR: In this article, an analysis of 11 years of precision radial velocity measurements of 76 nearby solar-type stars from the Lick radial velocity survey is presented, where the authors report on variability, periodicity, and long-term velocity trends.
Journal ArticleDOI

TL;DR: In this paper, the authors present a statistical analysis that demonstrates that the overwhelming majority of Kepler candidate multiple transiting systems (multis) indeed represent true, physically associated transiting planets.

TL;DR: Agarwal et al. as mentioned in this paper used asteroseismology to determine fundamental properties for 66 Kepler planet-candidate host stars, with typical uncertainties of 3% and 7% in radius and mass, respectively.
