Floquet analysis of disk instabilities and superhumps in Cataclysmic Variables
We analyze the dynamical stability of hydrodynamical flows in the equatorial plane of a thin axisymmetric accretion disk in close binary systems. The periodic tidal forces of the companion star induce parametric instabilities, which are characterized by the Floquet exponent. We propose that the onset of superhumps can be understood in this context. Comparing our model with well-known systems le...
متن کاملCataclysmic variables
Cataclysmic variables are binary stars in which a relatively normal star is transferring mass to its compact companion. This interaction gives rise to a rich range of behaviour, of which the most noticeable are the outbursts that give the class its name. Novae belong to the class, as do the less well known dwarf novae and magnetic systems. Novae draw their energy from nuclear reactions, while d...
متن کاملCataclysmic Variables from the Catalina Real-time Transient Survey
We present 855 cataclysmic variable candidates detected by the Catalina Real-time Transient Survey (CRTS) of which at least 137 have been spectroscopically confirmed and 705 are new discoveries. The sources were identified from the analysis of five years of data, and come from an area covering three quarters of the sky. We study the amplitude distribution of the dwarf novae CVs discovered by CR...
متن کاملCataclysmic variables in the ROSAT PSPC All Sky Survey
91 cataclysmic variables from a sample of 162 systems with known or suspected binary periods were detected during the ROSAT XRT-PSPC All Sky Survey. Among the non-magnetic systems, the X-ray to optical/ultraviolet flux ratio decreases along the sequence SU UMa type – U Gem type – Z Cam type – UX UMa type, due mainly to variations in the optical/ultraviolet flux. 8 of the 10 brightest systems in...
متن کاملThe Periods of Cataclysmic Variables
The present status of the period studies of cataclysmic variables is briefly reviewed, mainly from the observational point of view. A few comments on individual objects include EM Cyg, Z Cha, WZ Sge and AM CVn.
