Magnetic Cataclysmic Variables [PDF]
AIP Conference Proceedings, 2010 We present a study on magnetic cataclysmic variables (polars) using the collected data from the literature. These parameters (mass, radius, magnetic field intensity, mass transfer rate, etc.) and the relations between them are important to understand their nature, to explain the observed properties of them and to test the current evolutionary models.

Transients from the Cataclysmic Deaths of Cataclysmic Variables [PDF]
The Astrophysical Journal, 2021 Abstract We explore the observational appearance of the merger of a low-mass star with a white dwarf (WD) binary companion. We are motivated by recent work finding that multiple tensions between the observed properties of cataclysmic variables (CVs) and standard evolution models are resolved if a large fraction of CV binaries merge as a ...

The Galactic kinematics of cataclysmic variables [PDF]
Astrophysics and Space Science, 2015 Kinematical properties of CVs were investigated according to population types and orbital periods, using the space velocities computed from recently updated systemic velocities, proper motions and parallaxes. Reliability of collected space velocity data are refined by removing 34 systems with largest space velocity errors.

Contemporary Physics, 2006 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.

Cataclysmic Variable Stars [PDF]
International Astronomical Union Colloquium, 1984 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.

The Periods of Cataclysmic Variables [PDF]
International Astronomical Union Colloquium, 1987 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.

Suzaku View of Magnetic Cataclysmic Variables
Acta Polytechnica CTU Proceedings, 2015 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 ...

Theoretical spectra of cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 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.

Accretion in magnetic cataclysmic variables [PDF]
Astrophysics and Space Science, 1987 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
