恒星内部核反应系统中g-T效应产生的振荡

Oscillations excited by g-T effect in the core nuclear reaction system of stars

研究了恒星内部核反应系统中与粒子数密度涨落有关的振荡现象,分析了这类振荡的产生条件和特征频率。结果表明,引力及温度梯度(g-T)效应可以在氦核反应扩散模型中产生超临界的密度振荡。

Oscillations related to density fluctuation of particle number in the core nuclear reaction system of stars are investigated.It is shown that the supercritical density oscillations could be excited by gT effect in the model for helium nuclear reactiondiffusion system inside stars.The characteristic frequencies and producing criterion for the oscillations are analyzed.
