一个等级三星的一级动力学模型及其应用

A first-order dynamical model of hierarchical triple stars and its application

Xingbo Xu, Fang Xia, Yanning Fu

摘要:

对于大多数等级三星,经典的零级双二体模型在现有的观测精度下无法描述其组成部分的运动。在本文中,Marchal的一阶解析解的实现和一个更有效的简化版本被应用到真正的三星。结果表明,对于大多数三星,无论是对观测数据的拟合还是对组分位置的预测,一阶模型都优于零阶模型。

英文摘要:

For most hierarchical triple stars, the classical double two-body model of zeroth-order cannot describe the motions of the components under the current observational accuracy. In this paper, Marchal's first-order analytical solution is implemented and a more efficient simplified version is applied to real triple stars. The results show that, for most triple stars, the proposed first-order model is preferable to the zeroth-order model both in fitting observational data and in predicting component positions.
