VizieR Online Data Catalog: ROSAT data of Nearby Stars (Huensch+ 1999)
Abstract
We present X-ray data for all entries of the Third Catalogue of Nearby Stars (Gliese and Jahreiss, 1991, Cat. <V/70>) 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. (1 data file).
