The accretion geometry of intermediate polars (DQ her stars)
Abstract
Magnetic cataclysmic binaries in which the white dwarf is not phase-locked to the orbital motion but rotates such that the period of spin is less than the orbital period, usually referred to as DQ Her stars or intermediate polars, are discussed. Observations of one particular intermediate polar, EX Hya, which is the only member of the class presently known which is both an eclipsing system and a detected X-ray source, are highlighted. The accretion geometry of EX Hya is examined and ideas based on this geometry are extended to other members of the class.
