[Abstract]: Doppler velocity measurements from the Anglo-Australian Planet Search re-
veal planetary mass companions to HD23127, HD159868, and a possible second
planetary companion to HD154857. These stars are all G dwarfs. The com
panions are all in eccentric orbits with periods ranging from 1.2 to > 9.3 yr,
minimum (M sin i) masses ranging from 1.5 to > 4.5MJ, and semimajor axes be
tween 1 and > 4.5AU. The orbital parameters are updated for the inner planet
to HD154857, while continued monitoring of the outer companion is required to
confirm its planet status.
