Five Planets Orbiting 55 Cancri
Debra A. Fischer, Geoffrey W. Marcy, R. Paul Butler +9
We report 18 years of Doppler shift measurements of a nearby star, 55 Cancri, that exhibit strong evidence for five orbiting planets. The four previously reported planets are stron…
Three-Dimensional Simulations of Kelvin-Helmholtz Instability in Settled Dust Layers in Protoplanetary Disks
Joseph A. Barranco
As dust settles in a protoplanetary disk, a vertical shear develops because the dust-rich gas in the midplane orbits at a rate closer to true Keplerian than the slower-moving dust-…

J. D. Hartman, B. S. Gaudi, M. J. Holman +6
We have conducted a deep ($15 \la r \la 23$), 20 night survey for transiting planets in the intermediate age open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD cam…
A Search for Binary Stars at Low Metallicity
David K. Lai, Sara Lucatello, Michael Bolte +2
We present initial results measuring the companion fraction of metal-poor stars ([Fe/H]2.0). We are employing the Lick Observatory planet-finding system to make high-precision…
The Sloan Digital Sky Survey-II Supernova Survey: Technical Summary
Joshua A. Frieman, B. Bassett, A. Becker +98
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (…
Two Jovian-Mass Planets in Earthlike Orbits
Sarah E. Robinson, Gregory Laughlin, Steven S. Vogt +7
We report the discovery of two new planets: a 1.94 M_Jup planet in a 1.8-year orbit of HD 5319, and a 2.51 M_Jup planet in a 1.1-year orbit of HD 75898. The measured eccentricities…
Taking the Measure of the Universe: Precision Astrometry with SIM PlanetQuest
Stephen C. Unwin, Michael Shao, Angelle M. Tanner +33
Precision astrometry at microarcsecond accuracy has application to a wide range of astrophysical problems. This paper is a study of the science questions that can be addressed usin…
HAT-P-3b: A heavy-element rich planet transiting a K dwarf star
G. Torres, G. A. Bakos, G. Kovacs +13
We report the discovery of a Jupiter-size planet transiting a relatively bright (V = 11.56) and metal-rich early K dwarf star with a period of about 2.9 days. On the basis of follo…
A New Planet Around an M Dwarf: Revealing a Correlation Between Exoplanets and Stellar Mass
John A. Johnson, R. Paul Butler, Geoffrey W. Marcy +4
We report precise Doppler measurements of GJ317 (M3.5V) that reveal the presence of a planet with a minimum mass Msini = 1.2 Mjup in an eccentric, 692.9 day orbit. GJ317 is only th…
Self-Similar Solutions of Viscous-Resistive ADAFs With Poloidal Magnetic Fields
J. Ghanbari, F. Salehi, S. Abbassi
We carry out the self-similar solutions of viscous-resistive accretion flows around a magnetized compact object. We consider an axisymmetric, rotating, isotheral steady accretion f…
