Abstract

The paper presents high-precision radial velocity observations of the candidate planetary system HD 114762. The data obtained confirm Latham et al.'s (1989) of the binary nature of the system. The new orbital solution gives an eccentricity of 0.38 compared with the Latham et al. value of 0.25, but otherwise it agrees well with the discovery orbit. The mass function for the system implies a companion object with Mc sin i(orb) = 0.011 solar mass.
