Four New Exoplanets and Hints of Additional Substellar Companions to Exoplanet Host Stars
J. T. Wright, G. W. Marcy, D. A. Fischer +8
We present four new exoplanets: HIP 14810 b & c, HD 154345 b, and HD 187123 c. The two planets orbiting HIP 14810, from the N2K project, have masses of 3.9 and 0.76 M_jup. We have…
New Debris Disks Around Nearby Main Sequence Stars: Impact on The Direct Detection of Planets
C. Beichman, G. Bryden, K. Stapelfeldt
Using the MIPS instrument on the Spitzer telescope, we have searched for infrared excesses around a sample of 82 stars, mostly F, G, and K main-sequence field stars, along with a s…
A Long-Period Jupiter-Mass Planet Orbiting the Nearby M Dwarf GJ849
R. Paul Butler, John A. Johnson, Geoffrey W. Marcy +3
We report precise Doppler measurements of GJ849 (M3.5V) that reveal the presence of a planet with a minimum mass of 0.82 Mjup in a 5.16 year orbit. At a = 2.35 AU, GJ849b is the fi…
Catalog of Nearby Exoplanets
R. P. Butler, J. T. Wright, G. W. Marcy +8
We present a catalog of nearby exoplanets, available at http://exoplanets.org and ApJ 646, 505 (published version available at the link above). It contains the 172 known low mass c…
Precise Radial Velocities of Giant Stars II. Pollux and its Planetary Companion
Sabine Reffert, Andreas Quirrenbach, David S. Mitchell +5
It has long been speculated that the observed periodic radial velocity pattern for the K giant Pollux might be explained in terms of an orbiting planetary companion. We have collec…
Precise radial velocities of giant stars: I. Stable stars
S. Hekker, S. Reffert, A. Quirrenbach +4
Context: Future astrometric missions such as SIM PlanetQuest need very stable reference stars. K giants have large luminosities, which place them at large distances and thus the ji…
