We also try to give a new definition about the AGB stars. We may refer TPAGB stars as homology AGB stars and the second ignition of hydrogen is an appropriate criterion of the HAGB, since after the second ignition of hydrogen, AGB stars have similar properties and structures: a degenerate CO core covered by double thin burning shells.
我们还尝试着给出一个有关AGB星的新的定义,即可以将热脉动AGB星称做相似AGB星,把恒星是否经历氢的第二次点燃看作恒星是否处于相似AGB的判据,因为在氢的第二次点燃之后,AGB星具有相似的性质和结构:一个简并的碳氧核上面覆盖着两层很薄的燃烧壳层。
