论文摘要
恒星形成是银河进化的基本过程。在过去的几十年中，一个问题是确定恒星形成是由外部触发器诱导还是在封闭系统中自我调节。外部触发器的作用可以有效地收集少量的质量，引起了与大规模恒星簇的形成有关的特别关注，这可能导致Starbursts。最近的观察结果表明，附近相互作用星系中的云云碰撞引起了巨大的聚类形成，包括麦哲伦系统和触角星系以及几乎所有众所周知的高质量恒星形成区域，例如RCW 120，M20，M20，M42，M42，NGC 6334等。理论上的工作为导致大规模簇/恒星形成的质量压缩奠定了基础。在这里，我们回顾了云云碰撞的最新进展并触发了恒星群集的形成，并讨论了这一研究领域的未来前景。
Star formation is a fundamental process for galactic evolution. One issue over the last several decades has been determining whether star formation is induced by external triggers or is self-regulated in a closed system. The role of an external trigger, which can effectively collect mass in a small volume, has attracted particular attention in connection with the formation of massive stellar clusters, which in the extreme may lead to starbursts. Recent observations have revealed massive cluster formation triggered by cloud-cloud collisions in nearby interacting galaxies, including the Magellanic system and the Antennae Galaxies as well as almost all well-known high-mass star-forming regions such as RCW 120, M20, M42, NGC 6334, etc., in the Milky Way. Theoretical efforts are laying the foundation for the mass compression that causes massive cluster/star formation. Here, we review the recent progress on cloud-cloud collisions and triggered star-cluster formation and discuss the future prospects for this area of research.
