摘要：

When massive stars approach the Eddington limit, their outer envelopes and winds become dominated by 'opacity peaks', i.e. by material properties. We discuss the physical consequences, namely the formation of strong Wolf-Rayet (WR) type winds and a radial extension of the stellar envelopes. The understanding of the physical processes in this regime is of basic importance for key phases of stellar evolution, such as the WR and LBV stage, and thus for questions on how massive stars evolve and how they end their lives.
