AbstractWe present results from IUE and optical spectra, optical photometry and circular polarimetry during high and low states of the highly luminous soft X-ray cataclysmic variable AR UMa that identifies the primary in this system as a white dwarf with a magnetic field of 230 MG. The high magnetic field likely threads accretion blobs all the way from the secondary to below the surface of the white dwarf, resulting in a lack of polarised cyclotron emission and an extreme soft-X-ray luminosity during the high state.

The Continuum

AbstractA new program for the calculation of theoretical spectra and wavelength dependend degrees of the linear and circular polarization for magnetic white dwarfs with hydrogen atmospheres has been developed. The main improvement compared to previous models is a more realistic treatment of the bound-free absorption and of the magnetooptical parameters arising from free electrons in the continuum. For the newly discovered magnetic white dwarf HS 1254+3430 a polar field strength of 18 MG was found. Calculations for the high field object Grw +70°8247 confirms the results of Wickramasinghe and Ferrario (320 MG) but gave a better fit to the spectrum at wavelengths larger than 6200 Å.
