Revised and updated catalogue of Byurakan-IRAS stars

Context.Five lists of late-type stars were published in Astrophysics in 1997–2001, found in the First Byurakan Survey low-dispersion spectroscopic plates as optical identifications of unidentified IRAS sources. These identifications were carried out in the region with $\delta> +61\degr$ and $|b|> 15 \degr$ with a surface of 1504 deg2. As a result, the catalogue of the Byurakan-IRAS Stars (BIS) was compiled. Its preliminary version has been available at the CDS since 2003. Aims.We revised and updated the BIS catalogue with the new data from recently published optical and infrared catalogues to give access to all available data and make further comparative studies of the properties of these objects possible. Methods.We made cross-correlations of the BIS catalogue with the MAPS, USNO-B1.0, and 2MASS, added updated SIMBAD data for the BIS objects, and provided accurate DSS1 and DSS2 positions and revised photometry. We also checked the objects for proper motion and variability. A refined classification from low-dispersion spectra in the Digitized First Byurakan Survey (DFBS) was carried out. Results.The revised and updated catalogue of 276 Byurakan-IRAS stars (BIS) is presented. Conclusions.The BIS catalogue can be used to study a complete sample of IRAS-selected stars and to investigate individual objects.
