Multiple Time Scales in the Cataclysmic Variable MV Lyr
Abstract
Based on ubvri photometry, the increase of color indices with decreasing time scale is reported. The "colder" energy distribution has the nightly mean emission, the "hotter" - the quasi-periodic oscillations, and the hour-scale wave is in between. This behaviour resembles that of TT Ari (Tremko et al. 1996; Andronov et al. 1999), and may be explained by a model in which the quasi-periodic oscillations originate in the relatively hot inner parts of the accretion disk.
