J/A+A/539/A51       Catalogue enriched with R CrB stars        (Tisserand, 2012)

Tracking down R Coronae Borealis stars from their mid-infrared WISE colours. Tisserand P. <Astron. Astrophys. 539, A51 (2012)> =2012A&A...539A..51T

It was created to list objects that have similar near- and mid-infrared characteristics than R Coronae Borealis (RCB) stars which are supergiant and hydrogen-deficient stars known to possess a hot circumstellar shell. It is therefore a catalogue enriched with RCB stars and further spectroscopic follow-ups are needed to reveal the nature of each object. The catalogue was produced from a series of selection criteria on the infrared colour of sources published in the Preliminary WISE data release (2011). These sources spread over 57% of the entire sky. They have also all been detected in each J, H and K bands of the 2MASS catalogue. Description: For each object, the equatorial and Galactic coordinates are given, as well as all four WISE (Wright et al., 2010AJ....140.1868W, Cat. II/307), three 2MASS (Skrutskie et al., 2006, Cat. VII/233), three DENIS (Epchtein et al., 1994Ap&SS.217....3E, Cat. B/denis) magnitudes, and their related 1-sigma errors. The five USNO-B1 magnitudes (Monet et al., 2003, Cat. I/284) are also listed, but not the individual measurement error since they were not delivered in the original catalogue. If one magnitude was not available, its value was replaced by the number -99. Also, if more than one epoch were available in the DENIS or USNO-B1 catalogues for one particular object, only the epoch related to the brightest magnitudes were kept. The last column of the catalogue gives the SIMBAD classification, as of July 2011, found using a 5 arcsec matching radius. An underscore character was given to the objects that had no classification in SIMBAD. WISE data acquisition and reduction are discussed in Wright et al. (2010AJ....140.1868W) and in the Explanatory Supplement to the WISE Preliminary Data Release Products. There are four WISE bands, with central wavelengths at 3.4, 4.6, 12, and 22um. File Summary:
