| Abstract: |
The principle difficulties of radiative transfer in expanding atmospheres are discussed. Standard methods of calculating the radiation field in lines (Sobolev approach, Comoving frame method, Monte Carlo simulation) are compared and the influence of line-blocking and multi-line (ML) processes on the radiation field is investigated. It turns out that ML processes can, in principle, accelerate the winds of WR stars even at large distances from the star. Finally, a newly developed operator is presented which is able to solve for all aspects of the radiation field in one single step. |
