Revised and Updated Catalogue of the First Byurakan Survey Blue Stellar Objects

Eleven lists of blue stellar objects (BSOs) were published in Astrophysics in 1990-1996, found in the First Byurakan Survey (FBS) low-dispersion spectroscopic plates. The selection was carried out in the region with +33° > δ > +45° and δ > +61° with a surface of 4000 deg². As a result, the catalogue of the FBS BSOs was compiled. Its preliminary version has been available at Centre de Données Astronomiques de Strasbourg since 1999. We revised and updated the FBS BSOs catalogue with new data from recently published optical and multiwavelength catalogs to give access to all available data and make further comparative studies of the properties of these objects possible. We made cross-correlations of the FBS BSOs catalogue with the Minnesota Automated Plate Scanner, USNO-B1.0, Sloan Digital Sky Survey, and Two Micron All Sky Survey, as well as ROSAT, IRAS, NRAO VLA Sky Survey¹The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc., and Faint Images of the Radio Sky at Twenty cm catalogs, added updated SIMBAD and NED data for the objects, and provided accurate DSS1 and DSS2 positions and revised photometry. We also checked the objects for proper motion and variability. A refined classification for the low-dispersion spectra in the Digitized First Byurakan Survey was carried out. The revised and updated catalogue of 1101 FBS BSOs is presented. The FBS BSOs catalogue can be used to study a complete sample of white dwarfs, hot subdwarfs, HBB stars, cataclysmic variables, bright active galactic nuclei, and to investigate individual interesting objects.
