Variability in the ROSAT All-Sky Survey
Listed in IVOA Registry (Virtual Observatory)
We present a systematic search for variability among the ROSAT All-Sky Survey (RASS) X-ray sources.
Description
We generated lightcurves for about 30000 X-ray point sources detected sufficiently high above background. For our variability study different search algorithms were developed in order to recognize flares, periods and trends, respectively.
The variable X-ray sources were optically identified with counterparts in the SIMBAD, the USNO-A2.0 and NED data bases, but a significant part of the X-ray sources remains without cataloged optical counterparts. A complete list of the 1207 variable sources we found is presented here.
