Abstract (from CDS):

Precise Doppler observations at Lick Observatory have revealed a substellar companion orbiting the F9 V star HD 136118 with an orbital period P=1209±24 days, velocity semiamplitude K=212±6 m.s–1, and eccentricity of 0.37±0.025. The assumed stellar mass of 1.24 M☉ yields a Keplerian companion with Msini=11.9 MJ and semimajor axis of 2.3 AU. We also confirm the orbital solutions for two previously announced planets, one orbiting the F8 V star HD 50554 and one orbiting the G0 V star HD 106252. Our orbital solution for HD 50554 yields P=1254±34 days, K=78.5±6.7 m.s–1, and e=0.51±0.06. The assumed stellar mass of 1.065 M☉ implies a companion mass Msini=3.7 MJ and semimajor axis of 2.2 AU. For HD 106252, we find P=1503.3±62 days, K=150.9±25 m.s–1, and eccentricity e=0.57±0.11. The assumed stellar mass of 0.96 M☉ implies Msini=6.96 MJ and semimajor axis of 2.42 AU.
