ROSAT All-Sky Survey: A-K Dwarfs/Subgiants
Listed in NASA Data Portal
This catalog presents X-ray data for all the 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 (also known as the HR Catalogue) that have been detected as X-ray sources in the ROSAT All-Sky Survey (RASS).
Description
A number of stars in the appropriate spectral type range that do not have assigned luminosity classes have also been included. The catalogue contains 980 such HR stars detected as X-ray sources out of a total of 3054 stars in the HR Catalogue that satisfy the selection criteris, implying an average detection rate of 32%.
In addition to the measured ROSAT PSPC count rates, source detection parameters, hardness ratios, and X-ray fluxes, X-ray luminosities derived from Hipparcos parallaxes are also listed. This database was created at the HEASARC in February 1999 based on the ADC/<a href="cdsarc.cds.unistra.fr/ftp/cats/J/A+AS/132/155">CDS Catalog J/A+AS/132/155</a>. This is a service provided by NASA HEASARC .
