The Magnetic white dwarfs in AM Her variables

  • D.T. Wickramasinghe (a1)

Extract

There are now some 15 cataclysmic variables that have been recognised as being of the AM Her type. They are characterised by the presence of variable circular and linear polarisation in the optical and IR spectral regions, approaching 40% in some systems. The polarized radiation has been attributed to high harmonic cyclotron emission from hot (∼ 5 – 30 Kev) plasma located at accretion shocks near the poles of a highly magnetised (∼ 20 – 60 MG) white dwarf primary. There is hope that the study of the rich variety of phenomena exhibited by these systems will eventually enable us to probe the magnetic field structure of the underlying white dwarfs, perhaps even in more detail than has been possible with the isolated magnetic white dwarfs (Wickramasinghe (1987), Schmidt (1987)).
