J/A+AS/118/481     ROSAT all-sky survey catalogue of OB stars (Berghoefer+ 1996)

The ROSAT all-sky survey catalogue of optically bright OB-type stars. Berghoefer T.W., Schmitt J.H.M.M., Cassinelli J.P. <Astron. Astrophys. Suppl. Ser. 118, 481 (1996)> =1996A&AS..118..481B (SIMBAD/NED BibCode)
ADC_Keywords: Stars, OB ; X-ray sources Mission_Name: ROSAT Keywords: stars: early-type - X-rays: stars Description: For the detailed statistical analysis of the X-ray emission of hot stars we selected all stars of spectral type O and B listed in the Yale Bright Star Catalogue and searched for them in the ROSAT All-Sky Survey. In this paper we describe the selection and preparation of the data and present a compilation of the derived X-ray data for a complete sample of bright OB stars. File Summary:
