双星复合星族合成：星团颜色－星等图研究的新趋势

摘要

本文介绍了星团颜色－星等图研究的新方法———双星复合星族合成，该方法通过加入双星星族来构建理论模型，并且考虑了多次星爆形成恒星的复合情况。通过使用该方法构建出来的几种理论星团颜色－星等图的例子可以看出，这些图形更加符合实际观测到的结果，因此，双星复合星族合成将成为研究星团颜色－星等图的新趋势。最后，简单介绍了它在研究星团颜色－星等图中的应用。%In this paper , a new method of color-magnitude diagrams of clusters , i.e.binary-star composite stellar population synthesis , is introduced.This theoretical model is constructed by taking binary-star stellar and many starbursts into account .We give some examples of the theoretical color-magnitude diagrams of clusters and have found that they are more consistent with the actual observation results .Therefore , binary-star composite stellar population synthesis will become a new trend for the study of color-magnitude diagrams of clusters .At last, the ap-plications of this method in color-magnitude diagrams of clusters are also briefly introduced .
