ROSAT All-Sky Survey: White Dwarfs
Listed in IVOA Registry (Virtual Observatory)
This database table lists all white dwarf stars, both previously-cataloged and newly discovered, which have been detected in the ROSAT All-Sky Survey.
Description
The positions and count rates of the X-ray sources associated with each star are given, as well as spectral types and other star names for those stars which have been previously cataloged. This database table also lists distances estimated via Balmer line profile fitting, corrected (for IS absorption) X-ray luminosities, and each star's contribution to the X-ray luminosity function for all DA white dwarfs which were detected in the ROSAT All-Sky Survey.
