| Abstract: |
We study the effects of optically thick clumps, non-void interclump medium,
variation of the onset of clumping, and velocity dispersion inside clumps on
the formation of resonance lines. For this purpose we developed a full
3-D Monte Carlo radiative transfer code that is able to handle 3-D
shapes of clumps and arbitrary 3-D velocity fields. The method we developed
allows us to take into account contributions from density and velocity wind
inhomogeneities to the total opacity very precisely. The first comparison
with observation shows that 3-D density and velocity wind inhomogeneities
have a very strong influence on the resonance line formation, and that they
have to be accounted for in order to obtain reliable mass-loss rate
determinations. |
