摘要: In the past decade, increasing sophistication of high resolution techniques from ground, and advent HST have allowed a systematic study outflows around evolved massive stars. It has been established (Nota & Clampin 1997) that most LBVs Ofpe/WN9 stars are surrounded by associated circumstellar nebulae which ejected in some previous phase their evolution. These fossil record interactions winds violent ejections likely shed outer layers. The morphology, kinematics chemical composition material us to gain deep insight ejection shaping mechanism.
