恒星形成区的动力学--哪些机制决定了团簇形成的效率?

The dynamics of star-forming regions - which mechanisms set the cluster formation efficiency?

J. M. Diederik Kruijssen

摘要:

在恒星形成、星团和星系的许多研究中,恒星形成的分数(团簇形成效率或CFE)是一个中心量。最近的研究结果表明,与流行的假设相反,CFE不是(唯一)由气体排出,但也受到原始环境的影响,尽管其精确的行为仍然未知。在这里,它是讨论哪些机制设置的CFE,最近取得的进展已经解开他们的贡献,并需要在不久的将来,以实现定量的理解CFE的研究。

英文摘要:

The fraction of star formation that results in bound stellar clusters (cluster formation efficiency or CFE) is a central quantity in many studies of star formation, star clusters and galaxies. Recent results suggest that contrary to popular assumption, the CFE is not (solely) set by gas expulsion, but is also influenced by the primordial environment, although its precise behaviour remains unknown. Here it is discussed which mechanisms set the CFE, which recent advancements have been made to disentangle their contributions, and which studies are needed in the near future to achieve a quantitative understanding of the CFE.
