Radial velocities of population II binary stars. I.
Radial velocities for 114 Hipparcos stars, mostly high transversevelocity binaries without previous radial velocity measurements, arepublished. Measurements are made with the CORAVEL-type radial velocityspectrometer. The accuracy of measurements is better than 1 km/s. Twostars, BD +30 deg 2129A and HD 117466AB are found to be radial velocityvariables, and three more stars, HD 119515A, HD 131597AB, and HD 153344,are possible radial velocity variables.
