TL;DR: In this paper, a spectroscopic catalog of 70,841 visually inspected M dwarfs from the seventh data release of the Sloan Digital Sky Survey is presented, which is cross-matched to Two Micron All Sky Survey infrared data, and contains photometric distances for each star.
Journal ArticleDOI
The California Planet Survey. I. Four New Giant Exoplanets
Andrew W. Howard,John Asher Johnson,Geoffrey W. Marcy,Debra A. Fischer,Jason T. Wright,David Bernat,Gregory W. Henry,Kathryn M. G. Peek,Howard Isaacson,Kevin Apps,Michael Endl,William D. Cochran,Jeff A. Valenti,Jay Anderson,Nikolai Piskunov +14 more
TL;DR: In this paper, the Doppler measurements of four stars obtained during the past decade at Keck Observatory by the California Planet Survey (CPS) were used to confirm the Keck detections and significantly refine the orbital parameters.
Journal ArticleDOI
Dynamics of Linear Perturbations in f(R) Gravity
TL;DR: In this paper, the authors consider predictions for structure formation from modifications to general relativity in which the Einstein-Hilbert action is replaced by a general function of the Ricci scalar.
