Radial Velocities of Population II Binary Stars. Ii.
Here we publish the second list of radial velocities for 91 Hipparcosstars, mostly high transverse velocity binaries without previous radialvelocity measurements. The measurements of radial velocities are donewith a CORAVEL-type radial velocity spectrometer with an accuracy betterthan 1 km/s. We also present the information on eight new radialvelocity variables -- HD 29696, HD 117466 AB, BD +28 4035 AB, BD +302129 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.
