Calculations of non-LTE radiative transfer in extended outflowing atmospheres using the Sobolev approximation for line transfer
Abstract
The code that we are developing for the empirical modelling of LBVs using the Sobolev approximation ] for the line transfer, yields accurate results that compare well with those obtained using the co-moving frame method. By including absorption by the continuum in the resonance region in addition to escape from the resonance region we get a much more accurate result for the hydrogen ground level population. The following properties make the code extremely fast:
