Abstract EN

The article presents a calculation of relative phases and relative magnitudes for bremsstrahlung and cyclotron emissions from radioactive accretion shocks onto binary Magnetic CVs (AM-Her systems).

The calculation is carried out for a 0.3 solar mass white dwarf primary star, having a field B* = 30MG, and accretion rate of Edd Lacc = 3.2x10 L-3 Here LEdd is the Eddington accretion luminosity.

Individual on-axis accretion funnels are investigated corresponding to large radii at which field lines strike the equatorial plane (a0 ≡ req / R* = 500, 300, 300, 200, 150, 100, and 80).

Results show a relatively low level cyclotron cooling, and thus permit decoupling.
