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 MJUP, two are brown dwarf candidates with M sin i ~ 30 MJUP, and three are low-mass stellar companions. Hipparcos astrometry reveals the orbital inclinations and masses for three of the (more massive) companions, and it provides upper limits to the masses for the rest. A new class of extrasolar… Expand
