Beyond the Iron Peak: r- and s-process Elemental Abundances in Stars with Planets
J. C. Bond,Dante S. Lauretta,C. G. Tinney,C. G. Tinney,R. P. Butler,Geoffrey W. Marcy,Hugh R. A. Jones,Brad D. Carter,Simon J. O'Toole,Jeremy Bailey +9 more
TL;DR: In this article, elemental abundances of 118 stars (28 of which are known extrasolar planetary host stars) observed as part of the Anglo-Australian Planet Search are presented, along with previously published abundances for C and Si.
Journal ArticleDOI
The Breakthrough Listen Search for Intelligent Life: Target Selection of Nearby Stars and Galaxies
Howard Isaacson,Andrew Siemion,Geoffrey W. Marcy,Matt Lebofsky,Danny C. Price,David MacMahon,Steve Croft,David DeBoer,Jack Hickish,Dan Werthimer,Sofia Z. Sheikh,Greg Hellbourg,J. Emilio Enriquez +12 more
TL;DR: The Breakthrough Listen search for extraterrestrial intelligence during the first year of observations at the Green Bank Telescope, Parkes Telescope and Automated Planet Finder was presented in this article, where the 60 nearest stars, all within 5.1 pc from the sun, were selected.
Journal ArticleDOI
The Transit Ingress and the Tilted Orbit of the Extraordinarily Eccentric Exoplanet HD 80606b
Joshua N. Winn,Andrew W. Howard,John Asher Johnson,Geoffrey W. Marcy,J. Zachary Gazak,Donn Starkey,Eric B. Ford,Knicole D. Colón,F. Reyes,Lisa Nortmann,Stefan Dreizler,S. C. Odewahn,William F. Welsh,Shimonee Kadakia,Robert J. Vanderbei,Elisabeth R. Adams,M. Lockhart,Ian J. M. Crossfield,Jeff A. Valenti,Ronald F. Dantowitz,Joshua A. Carter +20 more
TL;DR: In this article, the first detection of the transit ingress was reported, revealing the transit duration to be 11.64 +/- 0.25 hr and allowing more robust determinations of the system parameters.
Journal ArticleDOI
Fourteen New Companions from the Keck and Lick Radial Velocity Survey Including Five Brown Dwarf Candidates
Shannon G. Patel,Steven S. Vogt,Geoffrey W. Marcy,John Asher Johnson,Debra A. Fischer,Jason T. Wright,R. Paul Butler +6 more
TL;DR: In this paper, the radial velocities for 14 stars on the California and Carnegie Planet Search target list were fit with Keplerian orbits across a grid of fixed values for M sin i and period P, and the resulting χ^2_v surface was used to place constraints on m sin i, P and semimajor axis ǫ.
Journal ArticleDOI
Four new planets orbiting somewhat metal-enriched stars
C. G. Tinney,R. Paul Butler,Geoffrey W. Marcy,Hugh R. A. Jones,Alan J. Penny,Chris McCarthy,Brad D. Carter,J. C. Bond +7 more
TL;DR: In this paper, the detection of four new extra-solar planets from the Anglo-Australian Planet Search orbiting the somewhat metal-enriched stars HD73526, HD76700, HD30177 and HD2039 was reported.
