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.
| A radio and optical study of the interacting system NGC 5090-5091
The results of a radio and optical study of the interactingelliptical-spiral system NGC 5090-5091 are presented. The radio dataconsist of synthesis maps of 50-arcsec resolution constructed from dataobtained from the Fleurs and Molonglo synthesis telescopes. The mainconclusions to be drawn from the data are as follows. The rotation axisof NGC 5090 is most closely aligned with the photometric major axis. Theradio axis is inclined at about 70 deg to the rotation axis and isperpendicular to the line joining the two nuclei. The morphology of NGC5091 is consistent with tidal disruption by NGC 5090 in an initiallyunbound retrograde encounter. The interaction between NGC 5090 and NGC5091 may be responsible, via an inner Lindblad resonance, for enhancedfueling of the nuclear source in NGC 5090, and this may produce jetspropagating perpendicular to the orbital plane of NGC 5091.
