Title: Search for radial velocity variation in visual binary and multiple stars
Keyword(s): stars, binary, spectroscopic, radial velocities, ADS 7651
Pages: 83 -- 98

Abstract: 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.
