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.
| Photometry of eight magnetic peculiar A stars
The paper presents the photometry of eight magnetic Ap stars 63 And, CUVir, Beta CrB, Chi Ser, 52 Her, HD 111133, HD 147010, and HD 173650,most of which was obtained with the Phoenix 10-in. AutomatedPhotoelectric Telescope of the Fairborn Observatory. Special attentionis given to the results of period determinations, showing that thefailure to establish better periods is often due to inaccuracies andgaps in the photometry. The data obtained for HD 147010 validatesNorth's (1984) period of 3.9210 days.
| 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.
