A new cataclysmic variable star
Publications of the Astronomical Society of the Pacific, 1992We report spectrophotometric observation of a new cataclysmic variable star J 05.23, discovered as a byproduct of the Calan-Tololo Survey of quasars and Seyfert galaxies. From the ESO Quick Blue Chart we estimated a B magnitude of 17.5. The spectrum between 3200 and 6500 angstroms shows strong emission in the He I lambda-5876 angstroms, HBeta, HGamma ...

Three unusual cataclysmic variable stars
Nature, 1983A recent survey for variable objects1 using an automated search procedure detected a number of variables for which it was only possible to give a preliminary classification. Many of the sample have now been observed spectroscopically on a large telescope and definite classifications made.

Discovery of a Bow-shock Nebula Around the Z Cam-type Cataclysmic Variable SY Cancri
Astronomical JournalWe report the serendipitous discovery of a bow-shock nebula around the cataclysmic variable (CV) SY Cancri. In addition, SY Cnc lies near the edge of a faint Hα-emitting nebula with a diameter of about 15′ . The orientation of the bow shock is consistent

Magnetic wind braking drives the spin-down of low-mass stars and the evolution of most interacting binary stars. A magnetic braking prescription that was claimed to reproduce both the period distribution of cataclysmic variables (CVs) and the evolution ...

The study of cataclysmic variables - interacting binary stars containing a white dwarf accreting from an orbiting companion - is undergoing an exciting renaissance, as it embraces observations at all wavelengths. Cataclysmic variables allow, in particular, the direct and detailed study of equilibrium and non-equilibrium accretion discs; in turn these ...

Introduction to Cataclysmic Variable Stars
2016Cataclysmic Variables are semi-detached binaries consisting of a White Dwarf that accretes material from a companion star (usually a Red Dwarf) that transfers matter to the White Dwarf. In this chapter I give a description of cataclysmic variable stars, their composition, classification and spectral characteristics.

Optical Properties of Cataclysmic Variable Stars
1990An overview is given of the optical behavior of cataclysmic variables, including the various types, the canonical model of these close binary systems, the causes of eruptions, short-term variations, and orbital periods, and correlations of light curve parameters with physical properties.
