We report results of a search for planets around 530 main-sequence stars using the Keck HIRES spectrometer, which has provided Doppler precision of 3 m s-1 during the past 3 yr. We report six new strong planet candidates having complete Keplerian orbits, with periods ranging from 24 days to 3 yr. These are HD 10697, HD 37124, HD 134987, HD 177830, HD 192263, and HD 222582. We also provide updated orbital parameters for the previously announced planets around HD 187123, HD 195019, HD 201277, and… 

Seven New Keck Planets Orbiting G and K Dwarfs

Planetary mass companions orbiting seven nearby G and K dwarfs have been found from the Keck Precision Doppler Survey. A "51 Peg-like" planet orbiting HD 49674 has the smallest mass yet found, M sin

Four New Planets Orbiting Metal-enriched Stars

We report the detection of four new extrasolar planets from the Anglo-Australian Planet Search orbiting the metal-enriched stars HD 73526, HD 76700, HD 30177, and HD 2039. The planetary companion of

Two New Planets from the Anglo-Australian Planet Search

Precise Doppler measurements from the Anglo-Australian Telescope (AAT) UCLES spectrometer reveal periodic Keplerian velocity variations in the stars HD 160691 and HD 27442. HD 160691 has a period of

Two Substellar Companions Orbiting HD 168443

Precise Doppler measurements during 4.4 yr from the Keck/HIRES spectrometer reveal two superimposed Keplerian velocity variations for HD 168443 (G6 IV). A simultaneous orbital fit to both companions

Three Low-Mass Planets from the Anglo-Australian Planet Search

We report the detection of three new low-mass planets from the Anglo-Australian Planet Search. The three parent stars of these planets are chromospherically quiet main-sequence G dwarfs with

High-eccentricity planets from the Anglo-Australian Planet Search

We report Doppler measurements of the stars HD 187085 and HD 20782 which indicate two high eccentricity low-mass companions to the stars. We find HD 187085 has a Jupiter-mass companion with a �1000 d

Ten Low-Mass Companions from the Keck Precision Velocity Survey

Ten new companions have emerged from the Keck precision Doppler velocity survey, with minimum (M sin i) masses ranging from 0.8 MJUP to 0.34 M☉. Five of these are planet candidates with M sin i < 12

A Pair of Resonant Planets Orbiting GJ 876

Precise Doppler measurements during 6 yr from the Lick and Keck observatories reveal two planets orbiting GJ 876 (M4V). The orbital fit yields companion masses of M sin i = 0.56 and 1.89 MJ, orbital

Five New Multicomponent Planetary Systems

We report Doppler measurements for six nearby G- and K-type main-sequence stars that show multiple low-mass companions, at least one of which has planetary mass. One system has three planets, the

Planetary Companions to HD 136118, HD 50554, and HD 106252

Precise Doppler observations at Lick Observatory have revealed a substellar companion orbiting the F9 V star HD 136118 with an orbital period P = 1209 ± 24 days, velocity semiamplitude K = 212 ± 6 m
