Scientific paper

We have obtained PSPC spectra of the antidwarf novae MV Lyr and KR Aur. Both spectra can be fitted with simple continuum models; in particular, a blackbody best describes both spectra. For KR Aur, a power law is also a good match to the spectrum. For MV Lyr, the Einstein ~5-keV bremsstrahlung spectral model appears to be excluded by the PSPC data. The differences are unlikely to be the result of incomplete phase coverage between the observation epochs. Neither PSPC spectrum shows any evidence for line emission in contrast to a recent report on four dwarf novae.
