脉动变星的理论研究

本项目试图研究脉动变星如下几个理论问题：1）湍流对流的非各向同性对恒星脉动稳定性的影响。2）湍流介质散射和折射对恒星脉动稳定性的影响。3）红变星中脉动不稳定的g模。4）脉动模式的选择机制。5）变星脉动稳定性对恒星演化和金属丰度的依赖性。

The present project tries to study the following theoretical proplems in pulsating variable stars: 1) The effects of anisotropy of turbulent convection on the pulsation stability of stars, 2)The effects of scattering and refrection caused by turbulent medium on the pulsation stability of stars, 3)unstable g modes in the red variables, 4) the choise mechanism of modes, 5) the dependence of pulsation stability on the evolutionary status and metal abundance of stars.
