		| Abstract: | Modern stellar wind models should account for new effects that were
 traditionally ignored in classical model atmospheres. Among these
 effects are stellar magnetic fields, X-ray emission, and wind clumping.
 The X-rays strongly affect the ionization structure of the winds. In
 O-type supergiants, clumping must be accounted for in the models to
 derive correct stellar parameters from X-ray or UV spectroscopy. |
