摘要

本文研究了双星系统共线平衡点附近的平衡点和周期轨道族与次级天体的角速度、系统的质量比和次级天体的大小的关系。我们假设物体的引力场是在考虑主质量点和次质量点作为旋转质量偶极子的情况下建模的。该模型允许计算从平衡点L1和L2发出的平面和晕周期轨道的族。分析了这些族的稳定性和分岔，并将结果与约束三体问题（RTBP）的结果进行了比较。这些结果提供了双星系统附近动力学行为的概述。

NUMERICAL INVESTIGATIONS OF THE ORBITAL DYNAMICS AROUND A SYNCHRONOUS BINARY SYSTEM OF ASTEROIDS

In this article, equilibrium points and families of periodic orbits in the vicinity of the collinear equilibrium points of a binary asteroid system are investigated with respect to the angular velocity of the secondary body, the mass ratio of the system and the size of the secondary. We assume that the gravitational fields of the bodies are modeled considering the primary as a mass point and the secondary as a rotating mass dipole. This model allows to compute families of planar and halo periodic orbits that emanate from the equilibrium points L1 and L2. The stability and bifurcations of these families are analyzed and the results are compared with the results obtained with the restricted three-body problem (RTBP). The results provide an overview of the dynamical behavior in the vicinity of a binary asteroid system.
