原始双星演化与蓝离散星

Primordial Binary Evolution and Blue Stragglers

X. Chen, Z. Han

摘要:

在所有种群中都发现了蓝离散者。这些天体对恒星演化和恒星星族合成都很重要。许多证据表明,蓝离散星与原始双星有关。本文总结了双星演化与蓝离散星的联系,描述了不同演化通道的蓝离散星的特征,并给出了它们对双星总体合成的影响,如积分光谱能量分布、色星等图、比频、对颜色的影响等。

英文摘要:

Blue stragglers have been found in all populations. These objects are important in both stellar evolution and stellar population synthesis. Much evidence shows that blue stragglers are relevant to primordial binaries. Here, we summarize the links of binary evolution and blue stragglers, describe the characteristics of blue stragglers from different binary evolutionary channels, and show their consequences for binary population synthesis, such as for the integrated spectral energy distribution, the colour-magnitude diagram, the specific frequency, and the influences on colours etc..
