The Lick-Carnegie Survey: Four New Exoplanet Candidates

Stefano Meschiari, Gregory Laughlin, Steven S. Vogt +4

We present new precise HIRES radial velocity (RV) data sets of five nearby stars obtained at Keck Observatory. HD 31253, HD 218566, HD 177830, HD 99492 and HD 74156 are host stars…

Improving Transit Predictions of Known Exoplanets with TERMS

Stephen R. Kane, David Ciardi, Debra Fischer +7

Transiting planet discoveries have largely been restricted to the short-period or low-periastron distance regimes due to the bias inherent in the geometric transit probability. Thr…

Three-dimensional Disk-Planet Torques in a Locally Isothermal Disk

Gennaro D'Angelo, Stephen H. Lubow

We determine an expression for the Type I planet migration torque involving a locally isothermal disk, with moderate turbulent viscosity (~0.0005 < alpha < ~0.05), based on three-d…

Retired A Stars and Their Companions VI. A Pair of Interacting Exoplanet Pairs Around the Subgiants 24 Sextanis and HD200964

John Asher Johnson, Matthew Payne, Andrew W. Howard +10

We report radial velocity measurements of the G-type subgiants 24 Sextanis (=HD90043) and HD200964. Both are massive, evolved stars that exhibit periodic variations due to the pres…

Systemic: A Testbed for Characterizing the Detection of Extrasolar Planets. II. Numerical approaches to the Transit Timing Inverse Problem

Stefano Meschiari, Gregory Laughlin

Transit timing variations - deviations from strict periodicity between successive passages of a transiting planet - can be used to probe the structure and dynamics of multiple-plan…

The Effects of Metallicity, and Grain Growth and Settling on the Early Evolution of Gaseous Protoplanets

Ravit Helled, Peter Bodenheimer

Giant protoplanets formed by gravitational instability in the outer regions of circumstellar disks go through an early phase of quasi-static contraction during which radii are larg…
