云环境被认为在决定大质量恒星的形成机制中发挥着关键作用。在这篇文章中，我们回顾了最近形成的大质量恒星周围环境的物理特征。特别强调最近的高角分辨率观测，这些观测提高了我们对电离气体致密区域以及与发光 O 和 B 星相关的致密热分子核心的物理条件和运动学的了解。我们将证明，在过去十年中收集的大量数据使人们在了解大质量恒星形成和早期演化过程中发生的物理过程方面取得了重大进展。
Cloud environment is thought to play a critical role in determining the mechanism of formation of massive stars. In this contribution we review the physical characteristics of the environment around recently formed massive stars. Particular emphasis is given to recent high angular resolution observations which have improved our knowledge of the physical conditions and kinematics of compact regions of ionized gas and of dense and hot molecular cores associated with luminous O and B stars. We will show that this large body of data, gathered during the last decade, has allowed significant progress in the understanding of the physical processes that take place during the formation and early evolution of massive stars.
