A New Planet around an M Dwarf: Revealing a Correlation between Exoplanets and Stellar Mass
John Asher Johnson,R. Paul Butler,Geoffrey W. Marcy,Debra A. Fischer,Steven S. Vogt,Jason T. Wright,Kathryn M. G. Peek +6 more
TL;DR: In this paper, the authors reported precise Doppler measurements of GJ 317 (M3.5 V) that reveal the presence of a second Jupiter-mass planet with a minimum mass M_P sin i = 1.2 M_(Jup) in an eccentric, 692.9 day orbit.
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
Five Planets Orbiting 55 Cancri
Debra A. Fischer,Geoffrey W. Marcy,R. Paul Butler,Steven S. Vogt,Greg Laughlin,Gregory W. Henry,David Abouav,Kathryn M. G. Peek,Jason T. Wright,John Asher Johnson,Chris McCarthy,Howard Isaacson +11 more
TL;DR: In this paper, Cancri et al. presented an apparent orbital period of 260 days, placing it 0.78 AU from the star in the large empty zone between two other planets, and the velocity wobble amplitude of 4.9 m s s 1 implies a minimum planet massM sini ¼ 45:7 M�.

Retired a stars and their companions. iii. comparing the mass-period distributions of planets around a-type stars and sun-like stars
Brendan P. Bowler,John Asher Johnson,Geoffrey W. Marcy,Gregory W. Henry,Kathryn M. G. Peek,Debra A. Fischer,Kelsey I. Clubb,Michael C. Liu,Sabine Reffert,Christian Schwab,Thomas B. Lowe +10 more
TL;DR: In this paper, the authors present an analysis of ~5 years of Lick Observatory radial velocity measurements targeting a uniform sample of 31 intermediate-mass (IM) subgiants with the goal of measuring the occurrence rate of Jovian planets around (evolved) A-type stars and comparing the distributions of their orbital and physical characteristics to those of planets around Sun-like stars.
