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.
| Spectral types of 80 early-type stars of variable radial velocity
MK spectral types are given for 80 normal early-type stars of variableradial velocity. These spectral types were determined from spectrogramstaken with the Lick Observatory 0.9-m refractor during the years1957-58.
| Distance to the anti-center shell
High-resolution, high-sensitivity echelle spectra have been obtainedtowards early-type stars located within the boundaries of theAnti-Center Shell (ACS), an anomalous velocity H I structure in theanticenter region of the Galaxy. The observations indicate that theshell is certainly more distant than 500 pc, and quite possibly moredistant than 2500 pc. No anomalous velocity C II absorption featureswere detected. These results support the hypothesis that the ACS is theresult of collision of high-velocity clouds with the Galactic H I disk.
