Radial Velocities of Population II Binary Stars. Ii.

Abstract

Here we publish the second list of radial velocities for 91 Hipparcos stars, mostly high transverse velocity binaries without previous radial velocity measurements. The measurements of radial velocities are done with a CORAVEL-type radial velocity spectrometer with an accuracy better than 1 km/s. We also present the information on eight new radial velocity variables -- HD 29696, HD 117466 AB, BD +28 4035 AB, BD +30 2129 A, BD +39 1828 AB, BD +69 230 A, BD +82 565 A and TYC 2267-1300-1 -- found from our measurements. Two stars (HD 27961 AB and HD 75632 AB) are suspected as possible radial velocity variables.
