Abstract
We present simultaneous X‐ray (λpeak ~ 44 Å) and EUV (λpeak = 89Å) light curves for the magnetic cataclysmic variable QQ Vulpeculae, obtained with the EUVE satellite. We find that the unique shape of the X‐ray light curve is different from previously obtained X‐ray light curves of QQ Vul and provides evidence for two‐pole accretion. Detailed examination of the photometric data indicates that QQ Vul undergoes a stellar eclipse of the X‐ray–emitting region, indicative of a high binary inclination. We discuss possible implications for the nature of this system given the observed shape of its EUV and X‐ray light curves.
