恒星内部氦燃烧3α过程稳定性问题中流体静力平衡偏离产生的对流效应

Convective effect produced by deviation against hydrostatics equilibrium in stability of helium combustion 3α process in the stars

利用发展的描述恒星内部热核反应的非平衡动力学理论,分析了恒星内部氦燃烧3α过程中由于流体静力平衡的偏离导致的对流扰动运动对其稳定性的影响,获得了稳定性判据中对流效应的表达式。分析表明该效应对稳定性起破坏作用。

Nonequilibrium dynamics theory developed in reference [1] which describes thermonuclear reaction in the stars is used to analyse effects of convective perturbation movement produced by deviation against hydrostatics equilibrium in the stability of 3α process in helium combustion in the stars, the convective effect in the stability criterion is obtained, which has a damaging effect on the stability of the thermonuclear reaction.
