The ROSAT all-sky survey catalogue of the nearby stars

Abstract

We present X-ray data for all entries of the Third Catalogue of Nearby Stars \cite[(Gliese & Jahreiss 1991)]{gli91} that have been detected as X-ray sources in the ROSAT all-sky survey. The catalogue contains 1252 entries yielding an average detection rate of 32.9 percent. In addition to count rates, source detection parameters, hardness ratios, and X-ray fluxes we also list X-ray luminosities derived from Hipparcos parallaxes. Catalogue also available at CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html
