Pulkovo compilation of radial velocities for 35495 stars in a common system. Not Available
Age and metallicity of a globular cluster in the dwarf spheroidal galaxy DDO 78 We present the results of moderate resolution spectroscopy for aglobular cluster in the M81 group dwarf spheroidal galaxy DDO 78. TheDDO 78 globular cluster, 4 Milky Way globular clusters, spectroscopicand radial velocity standards were observed with the Long-slitspectrograph of the 6-m telescope (SAO RAS, Russia). Lickspectrophotometric indices were determined in the bandpasses adopted byBurstein et al. (\cite{Bur84}). We have derived the mean metallicity ofthe globular cluster in DDO78 to be [Fe/H] =-1.6 +/- 0.1 dex by takingthe weighted mean of metallicities obtained from the strength of severalabsorption features. We have estimated an age for the globular clusterof 9-12 Gyr similar to that found for the Galactic globular cluster NGC362, which resembles the DDO 78 cluster in its chemical abundance andintegrated spectrophotometric properties.
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.
Mesures de vitesses radiales. VII. Accompagnement AU sol DU programme d'observation DU satellite Hipparcos. Radial velocities. VII. Ground based measurements for Hipparcos. We publish 734 radial velocities of stars distributed in 28 fields of4x4deg. We continue the PPO series (Fehrenbach et al. 1987; Duflot etal. 1990 and 1992), using the Fehrenbach objective prism method.
