Forming Planetesimals by Gravitational Instability: II. How Dust Settles to its Marginally Stable State

Aaron T. Lee, Eugene Chiang, Xylar Asay-Davis +1

Dust at the midplane of a circumstellar disk can become gravitationally unstable and fragment into planetesimals if the local dust-to-gas density ratio mu is sufficiently high. We…

Forming Planetesimals by Gravitational Instability: I. The Role of the Richardson Number in Triggering the Kelvin-Helmholtz Instability

Aaron T. Lee, Eugene Chiang, Xylar Asay-Davis +1

Gravitational instability (GI) of a dust-rich layer at the midplane of a gaseous circumstellar disk is one proposed mechanism to form planetesimals, the building blocks of rocky pl…

Chromospheric Activity and Jitter Measurements for 2630 Stars on the California Planet Search

Howard Isaacson, Debra Ann Fischer

We present time series measurements of chromospheric activity for more than 2600 main sequence and subgiant stars on the California Planet Search (CPS) program with spectral types…

HAT-P-20b--HAT-P-23b: Four Massive Transiting Extrasolar Planets

G. Á. Bakos, J. Hartman, G. Torres +19

We report the discovery of four relatively massive (2-7MJ) transiting extrasolar planets. HAT-P-20b orbits a V=11.339 K3 dwarf star with a period P=2.875317+/-0.000004d. The host s…

On the Transit Potential of the Planet Orbiting iota Draconis

Stephen R. Kane, Sabine Reffert, Gregory W. Henry +4

Most of the known transiting exoplanets are in short-period orbits, largely due to the bias inherent in detecting planets through the transit technique. However, the eccentricity d…

Modeling Kepler transit light curves as false positives: Rejection of blend scenarios for Kepler-9, and validation of Kepler-9d, a super-Earth-size planet in a multiple system

Guillermo Torres, François Fressin, Natalie M. Batalha +26

Light curves from the Kepler Mission contain valuable information on the nature of the phenomena producing the transit-like signals. To assist in exploring the possibility that the…

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…

HAT-P-18b and HAT-P-19b: Two Low-Density Saturn-Mass Planets Transiting Metal-Rich K Stars

J. D. Hartman, G. Á. Bakos, B. Sato +20

We report the discovery of two new transiting extrasolar planets. HAT-P-18b orbits the V=12.759 K2 dwarf star GSC 2594-00646, with a period P=5.508023+-0.000006 d, transit epoch Tc…

HAT-P-14b: A 2.2 Jupiter-mass exoplanet transiting a bright F star

G. Torres, G. A. Bakos, J. Hartman +16

We report the discovery of HAT-P-14b, a fairly massive transiting extrasolar planet orbiting the moderately bright star GSC 3086-00152 (V = 9.98), with a period of P = 4.627669 +/-…

Detection of a low-eccentricity and super-massive planet to the subgiant HD 38801

Hiroki Harakawa, Bun'ei Sato, Debra A. Fischer +7

We report the detection of a large mass planet orbiting around the K0 metal-rich subgiant HD38801 () by precise radial velocity (RV) measurements from the Subaru Telescope…

A Bayesian Periodogram Finds Evidence for Three Planets in 47 Ursae Majoris

Philip C. Gregory, Debra A. Fischer

A Bayesian analysis of 47 Ursae Majoris (47 UMa) radial velocity data confirms and refines the properties of two previously reported planets with periods of 1079 and 2325 days and…

M2K: I. A Jovian mass planet around the M3V star HIP79431

Kevin Apps, Kelsey I. Clubb, Debra A. Fischer +10

Doppler observations from Keck Observatory reveal the presence of a planet with Msini of 2.1 Mjup orbiting the M3V star HIP79431. This is the sixth giant planet to be detected in D…
