| Abstract: |
With the advance of stellar atmosphere modelling during the last few years, large progress in the understanding of Wolf-Rayet (WR) mass loss has been achieved. In the present paper we review the most recent developments, including our own results from hydrodynamic non-LTE model atmospheres. In particular, we address the important question of the Z-dependence of WR mass loss. We demonstrate that models for radiatively driven winds imply a rather strong dependence on Z. Moreover, we point out the key role of the L/M-ratio for WR-type mass loss. |
