摘要：

Doppler velocity measurements from the Anglo-Australian Planet Search reveal planetary mass companions to HD 23127, HD 159868, and a possible second planetary companion to HD 154857. These stars are all G dwarfs. The companions 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 > 4.5 MJ, and semimajor axes between 1 and > 4.5 AU. The orbital parameters are updated for the inner planet to HD 154857, while continued monitoring of the outer companion is required to confirm its planet status.
