摘要

摘要我们研究了恒星脉动研究中产生的一个涉及大参数的方程组，该方程组采用了多种方法来近似求解。我们介绍了奇异和非奇异扰动方法的组合，在符号计算的辅助下，这些方法在分析和天体物理学应用方面可能具有多学科的意义。示例软件采用 Wolfram 语言（Mathematica 13.2 版）。

An Application of Asymptotic Analysis in Linear Stellar Pulsation: a Case of Non-distinct Characteristic Roots

We study a system of equations, involving a large parameter, arising from the study of stellar pulsation for which a combination of procedures is used to approximate a fun damental solution. We present a combination of singular and non-singular perturbation methods which, aided by symbolic computation, may be of multi-disciplinary interest for the analysis as well as a astrophysics application. Example software is presented in the Wolfram Language (Mathematica version 13.2).
