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…
Two Exoplanets Discovered at Keck Observatory
J. A. Valenti, D. A. Fischer, G. W. Marcy +6
We present two exoplanets detected at Keck Observatory. HD 179079 is a G5 subgiant that hosts a hot Neptune planet with Msini = 27.5 M_earth in a 14.48 d, low-eccentricity orbit. T…
Five planets and an independent confirmation of HD 196885Ab from Lick Observatory
D. A. Fischer, P. Driscoll, H. Isaacson +9
We present time series Doppler data from Lick Observatory that reveal the presence of long-period planetary companions orbiting nearby stars. The typical eccentricity of these mass…
Refined stellar, orbital and planetary parameters of the eccentric HAT-P-2 planetary system
András Pál, Gáspár Á. Bakos, Guillermo Torres +10
We present refined parameters for the extrasolar planetary system HAT-P-2 (also known as HD 147506), based on new radial velocity and photometric data. HAT-P-2b is a transiting ext…
A Substellar Companion in a 1.3 yr Nearly-circular Orbit of HD 16760
Bunei Sato, Debra A. Fischer, Shigeru Ida +9
We report the detection of a substellar companion orbiting the G5 dwarf HD 16760 from the N2K sample. Precise Doppler measurements of the star from Subaru and Keck revealed a Keple…
HAT-P-13b,c: a transiting hot Jupiter with a massive outer companion on an eccentric orbit
G. A. Bakos, A. W. Howard, R. W. Noyes +15
We report on the discovery of a planetary system with a close-in transiting hot Jupiter on a near circular orbit and a massive outer planet on a highly eccentric orbit. The inner p…
The Frequency of Low-mass Exoplanets
S. J. O'Toole, H. R. A. Jones, C. G. Tinney +5
We report first results from the Anglo-Australian Telescope Rocky Planet Search - an intensive, high-precision Doppler planet search targeting low-mass exoplanets in contiguous 48…
Detectability of Terrestrial Planets in Multi-Planet Systems: Preliminary Report
Wesley A. Traub, Charles Beichman, Andrew F. Boden +21
We ask if Earth-like planets (terrestrial mass and habitable-zone orbit) can be detected in multi-planet systems, using astrometric and radial velocity observations. We report here…
HAT-P-12b: A Low-Density Sub-Saturn Mass Planet Transiting a Metal-Poor K Dwarf
J. D. Hartman, G. Á. Bakos, G. Torres +18
We report on the discovery of HAT-P-12b, a transiting extrasolar planet orbiting the moderately bright V=12.8 K4 dwarf GSC 03033-00706, with a period P = 3.2130598 +- 0.0000021 d,…
Old, Rich, and Eccentric: Two Jovian Planets Orbiting Evolved Metal-Rich Stars
Kathryn M. G. Peek, John Asher Johnson, Debra A. Fischer +10
We present radial velocity measurements of two stars observed as part of the Lick Subgiants Planet Search and the Keck N2K survey. Variations in the radial velocities of both stars…
The NASA-UC Eta-Earth Program: I. A Super-Earth Orbiting HD 7924
Andrew W. Howard, John A. Johnson, Geoffrey W. Marcy +8
We report the discovery of the first low-mass planet to emerge from the NASA-UC Eta-Earth Program, a super-Earth orbiting the K0 dwarf HD 7924. Keplerian modeling of precise Dopple…
HAT-P-11b: A Super-Neptune Planet Transiting a Bright K Star in the Kepler Field
G. Á. Bakos, G. Torres, A. Pál +21
We report on the discovery of HAT-P-11b, the smallest radius transiting extrasolar planet (TEP) discovered from the ground, and the first hot Neptune discovered to date by transit…
