Pulkovo compilation of radial velocities for 35495 stars in a common system.
Not Available
| 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.
| NGC 6366 - The most metal-rich halo globular cluster?
Spectra have been obtained at the Ca II IR triplet of four giants in theheavily reddened Galactic globular cluster NGC 6366. These spectra, whencompared with similar spectra of giants in the globular clusters NGC6171 and NGC 1851, suggest, for an adopted reddening of E(B-V) = 0.70mag, that the Fe/H = -0.84 + or - 0.23 dex for NGC 6366. It is concludedthat the Fe/H abundance of NGC 6366 is = -0.85 + or - 0.10 dex. Thespectra also yield a heliocentric velocity of -123.2 + or - 1.0 km/s forthe cluster. This velocity, when analyzed following the precepts ofArmandroff (1989), unambiguously associates NGC 6366 with the slowlyrotating halo cluster system, albeit the most metal-rich member of thispopulation yet identified, rather than with the rapidly rotating disksystem of globular clusters. An improved heliocentric velocity of -34 +or - 3 km/s is also given for NGC 6171, resolving the uncertaintyconcerning the velocity of this cluster.
