Cataclysmic Variable Stars [PDF]
AbstractThe properties of cataclysmic variable outbursts are reviewed, and interpreted in terms of dynamical instabilities by the red component, and subsequent evolution of the white dwarf accretion disc subject to a mass transfer burst in the transfer stream.

K-band spectroscopy of pre-cataclysmic variables [PDF]
Aims. There exists now substantial evidence for abundance anomalies in a number of cataclysmic variables (CVs), indicating that the photosphere of the secondary star incorporates thermonuclear processed material. However, the spectral energy distribution

Observations of three pre-cataclysmic variables from the Edinburgh-Cape blue object survey [PDF]
Aims: This study aims at determining the parameters of the three candidate pre-cataclysmic binaries EC 12477–1738, EC 13349–3237, and EC 14329–1625, most importantly their orbital period. Methods: Time-series photometry reveals orbital modulation in the

The Periods of Cataclysmic Variables [PDF]
AbstractThe 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.

Theoretical spectra of cataclysmic variables [PDF]
AbstractWe present two methods of modelling accretion disks in dwarf novae. The first one determines self-consistently the structure of a disk together with the radiation field. The computed theoretical spectra agree well with the observations of the dwarf nova WX Hyi in quiescence as well as in superoutburst.

Suzaku View of Magnetic Cataclysmic Variables
Results of magnetic cataclysmic variable studies performed with the Suzaku satellite are reviewed in this article. Particular emphasis is placed on the recent update of X-ray spectral model of intermediate polars, possible kinematically redshifted ...

Accretion in magnetic cataclysmic variables [PDF]
AbstractWe discuss the arguments in favour of the suggestion that polars (AM Her systems) and intermediate polars (IP’s) have magnetic fields of the same order of magnitude, and form one single class of objects. The period distribution of magnetic cataclysmic variables is well explained if they evolve the same way as non magnetic systems, IP’s becoming

Newly discovered cataclysmic variables from the INT/WFC photometric Hα survey of the northern Galactic plane [PDF]
We report the discovery of 11 new cataclysmic variable (CV) candidates by the Isaac Newton Telescope (INT) Photometric H alpha Survey of the northern Galactic plane (IPHAS).

Orbital periods of cataclysmic variables identified by the SDSS. VII, Four new eclipsing systems [PDF]
We present photometry of nine cataclysmic variable stars identified by the Sloan Digital Sky Survey, aimed at measuring the orbital periods of these systems. Four of these objects show deep eclipses, from which we measure their orbital periods. The light
