星团中星-星反射不均匀性的起源

Origin of Star-to-Star Abundance Inhomogeneities in Star Clusters

Jan Palouš, Richard Wünsch, Guillermo Tenorio-Tagle, Sergyi Silich

摘要:

一个新兴的大质量致密星团的年轻恒星重新插入的质量显示出双峰流体动力学行为。在星系团的内部,它是热不稳定的,而在它的外部,它形成了一个向外吹的风。低/高质量星团的化学均匀性/不均匀性表明了这种解决方案与单个/多个恒星星族存在的相关性。我们的后果,重新插入的质量的热不稳定性的银河系的超级风。

英文摘要:

The mass reinserted by young stars of an emerging massive compact cluster shows a bimodal hydrodynamic behaviour. In the inner part of the cluster, it is thermally unstable, while in its outer parts it forms an out-blowing wind. The chemical homogeneity/inhomogeneity of low/high mass clusters demonstrates the relevance of this solution to the presence of single/multiple stellar populations. We show the consequences that the thermal instability of the reinserted mass has to the galactic super-winds.
