Abstract:
We present radial-velocity (RV) measurements for the K giant stars
HD 25723, 17 Sco, 3 Cnc and 44 UMa, taken at the Lick Observatory
between 2000 and 2011. The best Keplerian fits to the data yield
minimum masses of 2.5MJup and 4.3MJup for the planets orbiting
HD 25723 and 17 Sco, respectively. The minimum masses of an additional
candidate around HD 25723, and of planet candidates around 3 Cnc and
44 UMa, would be 1.3MJup, 20.7MJup and 12.1MJup, respectively.
Description:
The radial velocities of HD 25723, 17 Sco, 3 Cnc and 44 UMa, measured
at Lick Observatory are presented. Their zero point is arbitrary.
