English Abstract
The thesis is a calculation of relative magnitudes and relative phases for Bremsstrahlung and cyclotron emissions from radiative accretion shocks onto binary Magnetic white dwarf star.
The calculation is being performed for a 3.0 solar mass star MS, having a magnetic field B* = 30MG and accretion rate of L acc = 3.2 x 10-3 LEdd.
Here LEdd is the Edenton accretion luminosity.
Eddington luminosity (sometimes also called the Eddington limit) which is defined as the point where the gravitational force inwards equals the continuum radiation force outwards, assuming hydrostatic equilibrium and spherical symmetry.
Using the mass-luminosity relation, it can be used to set limits on the maximum mass of a star.
If the luminosity of a star exceeds the Eddington luminosity of a layer on the stellar surface, , a star would initiate a very intense continuum driven stellar wind from its outer layers.
The phenomenon is named in honor of Sir Arthur Stanley Eddington. Individual off-axis accretion funnels are being investigated corresponding to radii at which field lines strike the equatorial plane (a o = r eq / R = 50, 33, 25, 20, 14 and 10).
