MV Lyrae in Low, Intermediate, and High States

We use analysis results from a low state of the VY Sculptoris system MV Lyrae, considered in an earlier paper (Hoard et al., 2004, ApJ, 604, 346), to study archival IUE spectra taken during an intermediate state and a HST spectrum taken during a high state. The intermediate state spectrum can be best fit by an isothermal accretion disk extending half way to the tidal cutoff radius. The high state spectrum can be best fit by a standard model extending from an inner truncation radius to an intermediate radius and an isothermal accretion disk beyond.
