Six new planets from the Keck precision velocity survey.

Abstract (from CDS):

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 HD 217107. Four of the six newly discovered planets have minimum Msini masses less than 2 MJUP, while the remaining two have Msini∼5 MJUP. The distribution of planetary masses continues to exhibit a rise toward lower masses. The orbital eccentricities of the new planets range from 0.12 to 0.71, which also continues the ubiquity of high eccentricities. All 17 known extrasolar planets orbiting beyond 0.2 AU have eccentricities greater than ∼0.1. The current limiting Doppler precision of the Keck Doppler survey is 3 m.s–1 per observation as determined from observations of both stable stars and residuals to Keplerian fits.
