论文摘要
在这项工作中,我们研究了由平面循环限制的三体问题建模的地球月底系统,并将其动力学特性与与特定不变歧管相关的基础结构相关联。我们考虑了一系列雅各比的恒定值,lagrangian Point $ L_1 $周围的颈部总是打开的,但由于山坡稳定性而构成轨道。首先,我们表明该系统在月球附近显示了三种不同的动态场景:两个混合的轨道,带有常规和混乱的轨道,两者之间几乎完全混乱。然后,我们使用单片矩阵理论分析了这些情况之间的过渡,并确定它们是由两种特定类型的分叉给出的。之后,我们说明了相位空间配置,尤其是稳定区域和粘性的形状,与lyapunov轨道的双曲线不变歧管本质上相关,也与某些特定不稳定的周期性轨道的折叠式旋转。最后,我们以描述动态诱捕的方式定义运输时间,并表明追踪的几何结构也连接到系统的传输特性。
In this work, we investigate the Earth-Moon system, as modeled by the planar circular restricted three-body problem, and relate its dynamical properties to the underlying structure associated with specific invariant manifolds. We consider a range of Jacobi constant values for which the neck around the Lagrangian point $L_1$ is always open but the orbits are bounded due to Hill stability. First, we show that the system displays three different dynamical scenarios in the neighborhood of the Moon: two mixed ones, with regular and chaotic orbits, and an almost entirely chaotic one in between. We then analyze the transitions between these scenarios using the Monodromy matrix theory and determine that they are given by two specific types of bifurcations. After that, we illustrate how the phase space configurations, particularly the shapes of stability regions and stickiness, are intrinsically related to the hyperbolic invariant manifolds of the Lyapunov orbits around $L_1$ and also to the ones of some particular unstable periodic orbits. Lastly, we define transit time in a manner that is useful to depict dynamical trapping and show that the traced geometrical structures are also connected to the transport properties of the system.
