Dwarf nova oscillations and quasi-periodic oscillations in cataclysmic variables - VI. Spin rates, propellering and coherence.
WARNER B. and PRETORIUS M.L.
Abstract (from CDS):
We suggest that the 28.95 s periodicity in WZ Sge, which has long been a puzzle, is caused by heated regions in the disc, just beyond the corotation radius, which are a consequence of magnetic coupling between the primary and gas in the accretion disc. This leads to a possible new interpretation of the `longer period DNOs' commonly observed in dwarf novae and nova-like variables.
