Scientific paper

Radial velocity measurements are given for 143 stars, predominantly for the components of visual binaries. A critical examination of the present and older observations extending over several decades indicates that the majority of the observed stars have a variable radial velocity. The cause of the radial velocity changes is the binary nature, multiplicity and/or the intrinsic variability of pulsating variable stars. Altogether 577 new radial velocity measurements are presented. For ADS 7651 the first RV curve is published.
