蓝离散星研究现状(Ⅱ):观测特性

The Status of Blue Straggler Studies(II): Observational Properties

不同恒星系统(银河系晕、疏散星团、球状星团、矮星系)中蓝离散星所表现出的观测特性各不相同,这与恒星系统动力学环境及相应的蓝离散星主导形成机制直接相关。因此,分析研究蓝离散星的不同观测特性,也就成为研究蓝离散星形成机制、恒星及双星系统演化以及恒星系统动力学演化的有效方法。

The observational features of blue stragglers （BSs） show great differences among the different stellar systems, such as Galactic halo, open clusters, globular clusters, and dwarf galaxies, These differences reveal the distinctive formation of BSs and the physical conditions of tile systems and their stellar populations, Therefore, studying the observational properties of BSs could be an effective method for studying the formation mechanisms of BSs, the evolution of single stars and binary systems, and the dynamical evolution of stellar systems,
