摘 要: | 本文从支配恒星内部物理过程的整套基本方程组出发,应用阵发混沌机制,研究其非线性特性,经过理论分析和数学演算,最后得出结论,即恒星结构方程本身,在一定参数范围内,能够自发出现阵发混沌脉动,这与已观测到的一些脉动变星的不规则光变性质,定性符合得很好。

Nonlinear Analysis in Pulsation Variable Star |

Abstract: | The nonlinear characterization in the basic equestions which described the structure of star is discussed by using intermittency mechanism.After some theoretical analysis and a few algebraic manipulations we find that the pulsation of intermittent chaos can occur spontaneously in the basic equations of star, within a certain parametric region. Such conclusion well agree with the observed irregularities in pulsation stars. |
