W Ursae Majoris contact binary variables as X-ray sources.

CHEN W.P., SANCHAWALA K. and CHIU M.C.

Abstract (from CDS):

We present cross-identification of archived ROSAT X-ray point sources with W UMa variable stars found in the All-Sky Automated Survey. A total of 34 W UMa stars have been found associated with X-ray emission. We compute the distances of these W UMa systems and hence their X-ray luminosities. Our data support the ``supersaturation'' phenomenon seen in these fast rotators, namely that the faster a W UMa star rotates, the weaker its X-ray luminosity.
