| Abstract: |
We have computed wind models with time-dependent dust formation and
grain-size dependent opacities, where (1) the problem is simplified by
assuming a fixed dust-grain size, and where (2) the radiation pressure
efficiency is approximated using grain sizes based on various means of
the actual grain size distribution. It is shown that in critical cases,
the effect of grain sizes can be significant. For well-developed winds,
however, the effects on the mass-loss rate and the wind speed are small. |
