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.
| Photometric observations and light curve analysis of the peculiar system ER Vulpeculae Photoelectric observations of the eclipsing variable ER Vul wereobtained in yellow and blue light. The light curve was analyzed and thephotometric elements were deduced using automated Fourier techniques onthe light changes. A new orbital period of the system (P = 0.698082days) is given. Absolute elements are derived and effective temperaturesof the two components are T(A) = 6000 K and T(B) = 5619 K.
