Accreting degenerate dwarfs comprise an important class of galactic X-ray sources. This has become evident with the recent discovery of soft and hard X-ray emission from accreting magnetic degenerate dwarfs such as AM Her, AN UMa, and 2A0311-23, and from nonmagnetic or weakly magnetic cataclysmic variables such as SS Cyg, U Gem, EX Hya, and GK Per (for an observational review, see Garmire 1979). Previously known low mass X-ray binaries such as Cyg X-2 and Sco X-1, as well as some of the “bulge” sources, may also be moderate luminosity nonmagnetic degenerate dwarfs (Kylafis and Lamb 1979; Branduardi et al. 1979). Finally, theory predicts (Fabian, Pringle and Rees 1976; Katz 1977; Kylafis and Lamb 1979) an as yet undiscovered class of low luminosity nonmagnetic degenerate dwarf X-ray sources having hard (Tobs ≳ 30–50 keV) spectra.
