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…
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…
