Ten new low mass companions have emerged from the Keck precision
Doppler velocity survey, with minimum (msini) masses ranging from
0.8 mjup to 0.34 msun. Five of these are planet candidates with
msini < 12 mjup, two are brown dwarf candidates with msini ~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 planet is
emerging, characterized by nearly circular orbits and orbital
radii greater than 1 AU. The planet HD 4208b appears to be a
member of this new class. The mass distribution of extrasolar
planets continues to exhibit a rapid rise from 10 mjup toward the
lowest detectable masses near 1 msat.
