XMM-Newton observations of the pre-polar HS 0922+1333.

Abstract (from CDS):

We report on [XMM-Newton and accompanying phase-resolved optical observations of HS0922+1333, one out of nine pre-polars. It shows X-ray and UV variability correlated with the visibility of the main accretion spot. The spectral X-ray properties reveal a low temperature thermal plasma of ∼1keV with FX more than one order of magnitude below the cyclotron flux. The UV data indicate a cool white dwarf with TWD<8000K. We refine the ephemeris and determine a distance of 140±50pc. The derived location of the accretion spots yield a magnetic field axis laying nearly in the orbital plane. Optical spectroscopy uncovers a highly active secondary.
