Magnetic Cataclysmic Variable: Intermediate Polar or DQ Herculis System. An M-dwarf star loses material to a white dwarf star. The material forms an accretion stream before swirling into an accretion disc. As the material in the accretion disc approaches the magnetic white dwarf, it is swept up by the magnetic field of the white dwarf forming accretion curtains which follow the magnetic lines of force. The magnetosphere of the white dwarf is tilted with respect to the orbital plane, causing the accretion curtain to split, the material following the shortest route along the magnetosphere. The material then crashes into the magnetic poles of the white dwarf, causing strong X-ray emissions.
