Journal ArticleDOI
Two jovian-mass planets in earthlike orbits
Sarah E. Robinson,Gregory Laughlin,Steven S. Vogt,Debra A. Fischer,R. Paul Butler,Geoffrey W. Marcy,Gregory W. Henry,Peter Driscoll,Peter Driscoll,Genya Takeda,John Asher Johnson +10 more
TL;DR: The radial velocity residuals of both stars have significant trends, likely arising from substellar or low-mass stellar companions as mentioned in this paper, and Markov chain Monte Carlo simulations based on the derived orbital parameters indicate that the radial velocities of these stars are consistent with circular planet orbits.
Journal ArticleDOI
A Planet in a Circular Orbit with a 6 Year Period
Brad D. Carter,R. Paul Butler,C. G. Tinney,Hugh R. A. Jones,Geoffrey W. Marcy,Chris McCarthy,Debra A. Fischer,Alan J. Penny +7 more
TL;DR: In this paper, a planet with a 6-year period orbiting the G5 dwarf HD 70642 has been detected using the 3.9 m Anglo-Australian Telescope, which is a member of the rarest group of known planets.
Journal ArticleDOI
Three low-mass planets from the Anglo-Australian planet search
C. G. Tinney,R. Paul Butler,Geoffrey W. Marcy,Geoffrey W. Marcy,Hugh R. A. Jones,Hugh R. A. Jones,A. Penny,A. Penny,Chris McCarthy,Chris McCarthy,Brad D. Carter,Debra A. Fischer,Debra A. Fischer +12 more
TL;DR: In this paper, the authors reported the detection of three new low-mass planets from the Anglo-Australian Planet Search (APS) dataset, which are chromospherically quiet main-sequence G dwarfs with metallicities ranging from roughly solar (HD 117618) to metal enriched (HD 102117).
Journal ArticleDOI
CHARACTERIZING THE COOL KOIs. VII. REFINED PHYSICAL PROPERTIES OF THE TRANSITING BROWN DWARF LHS 6343 C
Benjamin T. Montet,Benjamin T. Montet,John Asher Johnson,Philip S. Muirhead,Ashley Villar,Corinne Vassallo,Christoph Baranec,Nicholas M. Law,Reed Riddle,Geoffrey W. Marcy,Andrew W. Howard,Howard Isaacson +11 more
TL;DR: In this paper, the authors presented an updated analysis of LHS 6343, a triple system in the Kepler field which consists of a brown dwarf transiting one member of a widely separated M+M binary system.
Journal ArticleDOI
The california planet survey iv: a planet orbiting the giant star hd 145934 and updates to seven systems with long-period planets*
Y. Katherina Feng,Y. Katherina Feng,Jason T. Wright,Benjamin E. Nelson,Sharon X. Wang,Eric B. Ford,Geoffrey W. Marcy,Howard Isaacson,Andrew W. Howard +8 more
TL;DR: In this article, the authors present an update to seven stars with long-period planets or planetary candidates using new and archival radial velocities from Keck-HIRES and other telescopes.
