摘要

从对大质量恒星的模拟中，我们发现可以激发出规则的低振幅径向脉动。这种脉动在核心氢燃烧和早期核心氦燃烧演化阶段都遇到过。对于选定的四种模型，我们给出了v波段的光曲线。对这些结果进行了讨论，目的是指导观测，以识别和监测自然界中有规律脉动的变质量恒星。

Pulsations of Luminous Blue Variables

From simulations of massive stars we flnd regular low-amplitude radial pulsations can be excited. Such pulsations were encountered during core hydrogen burning as well as during the early core helium burning stage of evolution. For four selected models we present light curves in the V-band. The results are discussed with the aim to guide observations to identify and monitor such regularly pulsating variable massive stars in nature.
