AbstractA model of the cataclismic SS Cygni is discussed in this paper. Based on observational data we show that in such object called “Intermediate Polar” with magnetic field of the order of 106 Gauss two types of accretion onto a white dwarf are possible: disk accretion with formation of a “dead” disk with following cut through the magnitosphere and manifestation of short period bright outburst followed by the formation of hot corona from the rest of the disk. The newly formed configuration when corona and inflowing flux interact represents a hybrid between accretion disk and quasispheric nucleus where the magnetic dipole with the white dwarf is situated. The generation of condition for Rayleigh - Taylor instability in this envelope explains the appearence of the second type (continuous outbursts).
