The X-ray source in non-magnetic cataclysmic variables.

VAN TEESELING A., BEUERMANN K. and VERBUNT F.

Abstract (from CDS):

We have analysed all available rosat pspc observations of non-magnetic cataclysmic variables. The VY Scl and non-SU UMa systems have harder X-ray spectra than the SU UMa and UX UMa systems. The old nova RR Pic has a very soft X-ray spectrum and might not be an ordinary non-magnetic cataclysmic variable. There appears to be no clear correlation of the X-ray temperature, the emission measure, or the X-ray luminosity with the accretion rate. However, we have found an anti-correlation between the observable emission measure and the orbital inclination of the system, from which we conclude that the X-ray emitting region is close to the white dwarf and has a size smaller than the white dwarf radius.
