Mass-radius Relation for Magnetic White Dwarfs
Recently, several white dwarfs with very strong surface magnetic fields have been observed. In this paper we explore the possibility that such stars could have sufficiently strong internal fields to alter their structure. We obtain a revised white dwarf mass-radius relation in the presence of strong internal magnetic fields. We first derive the equation of state for a fully degenerate ideal ele...
متن کاملMagnetic Accretion Onto White Dwarfs
The influence of the magnetic field on process of the accretion onto White Dwarfs in Cataclysmic Variables (CVs) is discussed. Except for the Polars or AM Her objects, the strength of magnetic field can not be measured directly in CVs by modern techniques. But there is growing evidence that most of the types of Cataclysmic Variables classified on the basis of their observational characteristics...
متن کاملAccretion onto Magnetic White Dwarfs
Recent developments in the accretion onto magnetic white dwarfs are reviewed. Accreting magnetic white dwarfs display many of the characteristics of accreting systems of a galactic scale, with the advantage that in these systems the accreting material is collimated into a relatively well-determined 1-dimensional ow.
متن کاملProgress in Modeling Magnetic White Dwarfs
The analysis of magnetic white dwarfs has made considerable progress since the last white dwarf workshop: 1. It could be shown that neither the magnetic white dwarf Grw +70◦8247 (Jordan & Friedrich, 2001) nor LP 790−29 (Jordan & Friedrich 2002, Beuermann et al. 2002) are fast rotators (P < 10 min) but are rotating slowly (P > 20 years). 2. Automatic fitting procedures have been developed which ...
متن کاملAccretion on to Magnetic White Dwarfs
The Magnetic Cataclysmic Variables (MCVs) are close interacting binaries where mass is transferred from a late type secondary star to a magnetic white dwarf. Two modes of accretion can be identified depending on the strength of the magnetic field, the mass transfer rate and orbital parameters. (a) Disced Accretion: In the Intermediate polars (IPs), the mass transfer stream circularises and form...
