摘要：

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.
