Scientific paper

Results are presented for polarimetric, spectroscopic, and spectrophotometric observations of AM Her over the wavelength range from 3200 to 10,800 A. The data are used to develop the basic features of a model involving a slowly rotating magnetic white dwarf in a binary accretion system. A distance range is defined for AM Her, a total luminosity and an accretion rate are determined, and the star's likely mass and orbit are considered. The characteristics of the accretion flow onto the degenerate primary are discussed in terms of an accretion funnel that channels the accreted material to the magnetic poles. It is shown that under certain conditions a substantial conversion of infall energy to radiation may occur in the polar region and that intense optical cyclotron emission may originate within a few stellar radii from the surface. The region responsible for the observed strong Balmer-line and continuum emission is modeled numerically, with a best fit given by a temperature of 9600 K.
