The article provides information on the cataclysmic corpse found by Stuart P. Littlefair of University of Sheffield and his colleagues on the Sloan Digital Sky Survey. The star SDSS 1035 has an orbital period of 82 minutes, which is the expected minimum period for evolved cataclysmics. Based on the article, the white dwarf in SDSS 1035 was ordinary, but the donor object was below the hydrogen-burning limit, making it a brown dwarf. The discovery will help in finding other cataclysmic stars.

    Binary evolution theory predicts that accreting white dwarfs with substellar companions dominate the Galactic population of cataclysmic variables (CVs). In order to test these predictions, it is necessary to identify these systems, which may be difficult if the signatures of accretion become too...

    In this work we generate theoretical radial velocities (RVs) of accreting white dwarfs. We compare theoretical RVs with observed RVs to gain insight into which cataclysmic variable (CV) components may contribute to the curves of observed RVs. We present preliminary results.

    Recurrent novae (RNe) are a subclass of cataclysmic variables classified based on recorded observations of more than one nova outburst. They form a small, but heterogeneous group of objects, with 10 known members, that undergo classical nova-like outbursts, with the significant differences being...

    In this paper I deal with the WD0137-349 binary system consisting of a white dwarf (WD) and a brown dwarf (BD) in a close circular orbit of about 116 min. I, first, constrain the admissible range of values for the inclination i by noting that, from looking for deviations from the third Kepler...
