UBV beta Database for Case-Hamburg Northern and Southern Luminous Stars
A database of photoelectric UBV beta photometry for stars listed in theCase-Hamburg northern and southern Milky Way luminous stars surveys hasbeen compiled from the original research literature. Consisting of over16,000 observations of some 7300 stars from over 500 sources, thisdatabase constitutes the most complete compilation of such photometryavailable for intrinsically luminous stars around the Galactic plane.Over 5000 stars listed in the Case-Hamburg surveys still lackfundamental photometric data.
| BVR Photometry of Northern Galactic Plane Luminous Stars
CCD-based BVR photometry of 90 stars listed in Volumes II, III, and IVof the Case-Hamburg Catalog of Luminous Stars in the Northern Milky Wayis reported. This research was performed at the Lowell Observatory 31inch telescope, which, under an agreement with Northern ArizonaUniversity and the NURO Consortium, is operated 60% of the time as theNational Undergraduate Research Observatory.
| 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.
| Interstellar extinction in the area of the North America and Pelican Nebulae complex
Interstellar extinction is investigated in the area including the NorthAmerica Nebula, the Pelican Nabula, the dark cloud separating both thenebulae, and the nearby area south of Alpha Cygni. Determination ofspectral classes, absolute magnitudes, and color excesses of 249 starsis based on their photometry in the Vilnius seven-color photometricsystem. The distance of the dark cloud is found to be 550 + or - 100 pc.The area west of the Pelican Nebula and south of Alpha Cygni iscomparatively transparent at least up to 700 pc.
