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…
When do early-type galaxies form?
Roberto G. Abraham, Patrick J. McCarthy, Erin Mentuch +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys to measure the mass density function of morphologically selected early-type galaxies in the Gemini Deep Deep 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…
The Search for an Atmospheric Signature of the Transiting Exoplanet HD 149026b
Nassim Bozorgnia, Jonathan J. Fortney, Chris McCarthy +2
HD 149026b is a short-period, Saturn-mass planet that transits a metal-rich star. The planet's radius, determined by photometry, is remarkably small compared to other known transit…
HAT-P-1b: A Large-Radius, Low-Density Exoplanet Transiting one Member of a Stellar Binary
G. A. Bakos, R. W. Noyes, G. Kovacs +16
Using small automated telescopes in Arizona and Hawaii, the HATNet project has detected an object transiting one member of the double star system ADS 16402 AB. This system is a pai…
