仙王座β型变星脉动不稳定区

摘要

A series of linear stability analyses of the rad ial and low-degree non-radial p-modes are carried out for stellar models with initial masses in 6-30 M⊙. A β Cephei instability strip of limited size is found. It is much narrower than the theoretical results presented by other rese archers, and matches very well with observations.%对一系列初始质量为6-30 M⊙的恒星模型的径向和低 阶 非径向p模振荡进行了线性稳定分析。找到了一有限范围的仙王座β型变星脉动不稳定区， 该脉动不稳定区比现有其他研究者的理论结果都要窄，同观测符合得很好。
