星团系统的早期动力学演化

Early dynamical evolution of star cluster systems

Genevieve Parmentier

摘要:

剧烈的弛豫--原星团对残余恒星形成气体的动力学反应--是星团和星团系统演化过程中一个短暂但至关重要的插曲。由于它在很大程度上受到团簇形成和环境条件的驱动,就探测恒星形成和星系演化而言,它是一个潜在的高回报阶段。在这篇文章中,我回顾了团簇形成和环境条件如何影响年轻的星系团质量函数的形状,以及星系的恒星形成率与其年轻的最大质量的星系团的质量之间的关系。

英文摘要:

Violent relaxation -- the protocluster dynamical response to the expulsion of its residual star forming gas -- is a short albeit crucial episode in the evolution of star clusters and star cluster systems. Because it is heavily driven by cluster formation and environmental conditions, it is a potentially highly rewarding phase in terms of probing star formation and galaxy evolution. In this contribution I review how cluster formation and environmental conditions affect the shape of the young cluster mass function and the relation between the present star formation rate of galaxies and the mass of their young most massive cluster.
