We explore conditions and structure of accretion disks in short-period Cata- clysmic Variables (CVs), which have evolved beyond the period minimum. We show that accretion discs in systems with extreme mass ratios grow up to the size of corresponding Roche lobe and are relatively cool. In contrast, the viscosity and temperature in spiral arms formed as a result of a 2:1 resonance are higher and their contribution plays an increasingly important role. We model such discs and generate light curves… Expand

This study of SDSS0804 is primarily concerned with the double-hump shape in the light curve and its connection with the accretion disk in this bounce-back system. Time-resolved photometric andExpand
Photometry of the eclipsing cataclysmic variable SDSS J152419.33+220920.0
Aims. We present new photometry of the faint and poorly studied cataclysmic variable SDSS J152419.33+220920.0, analyze its light curve and provide an accurate ephemeris for this system. Methods.Expand

We redetermine the relationship between absolute magnitude and orbital period for dwarf novae, based on 46 stars with good distance estimates. This improves upon Warner's previous relation, buildingExpand
