Journal ArticleDOI
Far-Ultraviolet Spectroscopy of Magnetic Cataclysmic Variables*
S. Araujo-Betancor,Boris T. Gänsicke,Knox S. Long,Klaus Beuermann,D. de Martino,Edward M. Sion,Paula Szkody +6 more
TL;DR: In this paper, the authors used pure hydrogen WD models to fit the FUV spectra of the low-state systems (except RX J1554.2+2721, which is a high-field polar) in order to measure the WD effective temperatures.

TL;DR: In this paper, the authors presented time-series optical photometry of five new SW Sextantis stars identified by the Hamburg Quasar Survey, including HS 0805+3822, HS 0129+2933, HS 0220+0603, HS 0455+8315, and HS 0705+6122.
