TL;DR: Spectroscopic metallicities of the host stars of 226 small exoplanet candidates discovered by NASA's Kepler mission are reported, finding that planets with radii less than four Earth radii form around host stars with a wide range of metallicities (but on average a metallicity close to that of the Sun), whereas large planets preferentially form around stars with higher metallicities.
THE McDONALD OBSERVATORY PLANET SEARCH: NEW LONG-PERIOD GIANT PLANETS AND TWO INTERACTING JUPITERS IN THE HD 155358 SYSTEM
Paul Robertson,Michael Endl,William D. Cochran,Phillip J. MacQueen,Robert A. Wittenmyer,Jonathan Horner,Erik Brugamyer,A. E. Simon,A. E. Simon,Stuart I. Barnes,Caroline Caldwell +10 more
TL;DR: In this article, high-precision radial velocity (RV) observations of four solar-type (F7-G5) stars were taken as part of the McDonald Observatory Planet Search Program.
REVISITING ρ1 CANCRI e: A NEW MASS DETERMINATION OF THE TRANSITING SUPER-EARTH*
Michael Endl,Paul Robertson,William D. Cochran,Phillip J. MacQueen,Erik Brugamyer,Caroline Caldwell,Robert A. Wittenmyer,Stuart I. Barnes,Kevin Gullikson +8 more
TL;DR: In this paper, a mass determination for the transiting super-Earth ρ1 Cancri e based on nearly 700 precise radial velocity (RV) measurements is presented.
A second giant planet in 3:2 mean-motion resonance in the hd 204313 system
