Magnitudes of Bremsstrahlung and Cyclotron Cooling From on-Axis Accretion Shocks onto AM-Her Systems

The article presents a calculation of relative phases and relative magnitudes for bremsstrahlung and cyclotron emissions from radiative 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 lacc = 3.2x10^-3 ledd. 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.
