摘要
利用数值方法,对一类平面限制性四体问题作了探讨.找到了系统的平衡点解并研究了它们的性质.发现了平衡点的分岔现象.讨论了在不同系统参数下,第4体的可能运动区域的拓扑结构.
A kind of the planar restricted problem of 4-body is discussed by the numerical method. The equilibrium solutions of the problem are found and studied. The bifurcation of the equlibriums is discovered. And the topological structures of the region of possible motion of the fourth body are discussed with different system parameters.
