Radial velocities of population II binary stars. I.

Radial velocities for 114 Hipparcos stars, mostly high transverse velocity binaries without previous radial velocity measurements, are published. Measurements are made with the CORAVEL‐type radial velocity spectrometer. The accuracy of measurements is better than 1 km/s. Two stars, BD +30° 2129A and HD 117466AB are found to be radial velocity variables, and three more stars, HD 119515A, HD 131597AB, and HD 153344, are possible radial velocity variables.
