Velocities of 1253 F-K dwarfs in open clusters
Listed in IVOA Registry (Virtual Observatory)
A long-term monitoring of solar-type dwarfs in 13 nearby open clusters, d<500pc, was conducted during 19 years, but most individual radial velocities were not published, with the exception of a small number of spectroscopic binaries.
Description
The program was designed to study the membership, the duplicity, and to search for new members. We obtained 6070 radial velocities during 19 years at the Haute-Provence Observatory (France) and 1130 during 13 years at ESO La Silla (Chile) for 1253 stars in the field of 13 open clusters.
The zero point of the CORAVEL radial velocity system has been improved and the new values supersede those published previously. The membership and binarity of solar-type stars in NGC 1976 (Orion), IC 2602, NGC 7092, and NGC 2682 are briefly discussed. For the whole sample, we confirm the membership of 894 stars and discovered 150 new spectroscopic binaries among them.

Added to those already known in the Hyades and Coma Berenices, the number of member spectroscopic binaries amounts to 188. The overall binary frequency is 30% (188/618) for stars with at least 2 measurements. IC 2602 may represent an exception because no spectroscopic binaries were found among the 26 members.
New orbital elements were computed with the updated values of the radial velocities for 66 systems, representing 55 members and 11 non-members. This paper is the last one from our team reporting CORAVEL radial velocities of solar-type dwarfs in nearby open clusters. All CORAVEL observations for dwarfs and red giants in open clusters are now available in electronic form.
