Revised and updated catalogue of Byurakan-IRAS stars
Context.Five lists of late-type stars were published in Astrophysics in1997-2001, found in the First Byurakan Survey low-dispersionspectroscopic plates as optical identifications of unidentified IRASsources. These identifications were carried out in the region withδ> +61° and |b|> 15 ° with a surface of 1504deg2. As a result, the catalogue of the Byurakan-IRAS Stars(BIS) was compiled. Its preliminary version has been available at theCDS since 2003.Aims.We revised and updated the BIS catalogue withthe new data from recently published optical and infrared catalogues togive access to all available data and make further comparative studiesof the properties of these objects possible.Methods.We madecross-correlations of the BIS catalogue with the MAPS, USNO-B1.0, and2MASS, added updated SIMBAD data for the BIS objects, and providedaccurate DSS1 and DSS2 positions and revised photometry. We also checkedthe objects for proper motion and variability. A refined classificationfrom low-dispersion spectra in the Digitized First Byurakan Survey(DFBS) was carried out.Results.The revised and updated catalogueof 276 Byurakan-IRAS stars (BIS) is presented.Conclusions.The BIScatalogue can be used to study a complete sample of IRAS-selected starsand to investigate individual objects.
