cds-question@unistra.frgiant-starsdwarf-starsx-ray-sourcesWe present X-ray data for all main-sequence and subgiant stars of spectral types A, F, G, and K and luminosity classes IV and V listed in the Bright Star Catalogue (Cat. <V/50>) that have been detected as X-ray sources in the ROSAT all-sky survey; In addition to count rates, source detection parameters, hardness ratios, and X-ray fluxes we also list X-ray luminosities derived from Hipparcos parallaxes.1998A&AS..132..155Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/132/155CatalogResearchIsServedByTAP VizieR generic servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1996)IX/11 : ROSAT PSPC Source Catalog (Voges+ 1994)J/A+AS/127/251 : Giants and supergiants ROSAT data (Huensch+ 1998)J/A+AS/135/319 : Late-type main-sequence stars ROSAT data (Huensch+ 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/132/155https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/132/155http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/132/155https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/132/155https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/132/155http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/132/155GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapROSATX-raydefaultJ/A+AS/132/155/table2RASS detections of BSC late-type main-sequence starsrecnoRecord number assigned by the VizieR team.
