The California Planet Survey II. A Saturn-Mass Planet Orbiting the M Dwarf Gl649
John Asher Johnson, Andrew W. Howard, Geoffrey W. Marcy +6
We report precise Doppler measurements of the nearby (d = 10.34 pc) M dwarf Gl649 that reveal the presence of a planet with a minimum mass Msini = 0.328 Mjup in an eccentric (e = 0…
A Super-Earth and two Neptunes Orbiting the Nearby Sun-like star 61 Virginis
Steven S. Vogt, Robert A. Wittenmyer, R. Paul Butler +10
We present precision radial velocity (RV) data that reveal a multiple exoplanet system orbiting the bright nearby G5V star 61 Virginis. Our 4.6 years of combined Keck/HIRES and Ang…
A Super-Earth Orbiting the Nearby Sun-like Star HD 1461
Eugenio J. Rivera, R. Paul Butler, Steven S. Vogt +3
We present precision radial velocity data that reveal a Super-Earth mass planet and two probable additional planets orbiting the bright nearby G0V star HD 1461. Our 12.8 years of K…
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 +8
We present an analysis of ~5 years of Lick Observatory radial velocity measurements targeting a uniform sample of 31 intermediate-mass subgiants (1.5 < M*/Msun < 2.0) with the goal…
The Radial Velocity TATOOINE Search for Circumbinary Planets: Planet Detection Limits for a Sample of Double-lined Binary Stars - Initial Results from Keck I/Hires, Shane/CAT/Hamspec and TNG/Sarg Observations
Maciej Konacki, Matthew W. Muterspaugh, Shrinivas R. Kulkarni +1
We present preliminary results of the first and on-going radial velocity survey for circumbinary planets. With a novel radial velocity technique employing an iodine absorption cell…
The 8 Micron Phase Variation of the Hot Saturn HD 149026b
Heather A. Knutson, David Charbonneau, Nicolas B. Cowan +4
We monitor the star HD 149026 and its Saturn-mass planet at 8.0 micron over slightly more than half an orbit using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope.…
