恒星时代:水平分支

The Ages of Stars: The Horizontal Branch

M. Catelan

摘要:

水平分支(HB)恒星在“年龄争论”中扮演着特别重要的角色,因为它们是长期存在的“第二参数”问题的核心。在这篇综述中,我讨论了一些最近的进展,我们的理解的性质和HB星的起源。

英文摘要:

Horizontal branch (HB) stars play a particularly important role in the "age debate," since they are at the very center of the long-standing "second parameter" problem. In this review, I discuss some recent progress in our understanding of the nature and origin of HB stars.
