Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.
| Space motions of galactic G- and K-type stars
Spectra of 912 G- and K-type stars in six galactic directions have beensecured. The relevant space motions of the stars, subdivided intodistance groups, have been derived; these show no significant departuresfrom the mean motion of nearby stars. The velocity dispersions, ingeneral, indicate that these (mainly giant) stars are moderately old.The dispersion in u is lower than that for nearby stars, and thesignificance of this result is discussed.
