Recent Results from High Energy Observations of Cataclysmic Variables: AM Canum Venaticorum and DW Ursae Majoris

We present preliminary results from high energy observations of two cataclysmic variables that are prototypes of the classes to which they belong. The first is AM Canum Venaticorum, prototype of the AM CVn class of interacting binary white dwarfs. We have obtained average and time-resolved far-ultraviolet spectra of AM CVn with FUSE. The second is DW Ursae Majoris, one of the four founding members of the SW Sextantis class of novalike cataclysmic variable. We have observed DW UMa using XMM.
