Cepheids, Binaries: Spectroscopic

Scientific paper

Radial velocity measurements of classical Cepheids obtained by the CORAVEL and ELODIE spectrographs have been analysed. The comparison with earlier radial velocity data resulted in the discovery of eight new spectroscopic binaries (in the 9.7'-12.4' interval of mean V-brightness). An updated value of the pulsation period is also determined for the new SB-Cepheids.
