A model of a binary star system comprising a massive early-type star and a magnetic white dwarf is proposed to explain the emission features of the strong emission line object SS 433. The production of the greatly red- and blueshifted emission lines observed for SS 433 is accounted for by gaseous material in near co-rotation with the white dwarf at a distance of 10 million km above the polar caps of a dipole magnetic field aligned with or at a large angle to the spin axis. The periodicity of line merging is attributed to the nutation (or possibly precession) of the white dwarf induced by dissipative interaction with a fairly early type star of between one and 10 solar masses. Sources of radio and X-ray emission are also suggested.
