摘要

本文的主要目的是用数值方法研究广义摄动圆约束三体问题(GPCR3BP)中无穷小物体在各种类型摄动下的动力学运动特性。在三个天体中,一个较大的天体(称为初级天体)被视为具有辐射效应的扁圆形状,另一个较大天体(也称为次级天体)被认为具有反照率效应的三轴形状,第三个天体(被称为无穷小天体,比其他两个较大天体更小)正在改变其质量,假设了物体之间的相互作用和科里奥利以及离心力的影响。两个初级都在围绕原点的圆形轨道上运动,原点也是它们的共同质心。利用上面定义的扰动,我们确定了无穷小物体的运动方程和拟雅可比积分。我们数值计算了平衡点的位置(平面内和平面外)、运动区域、截面的庞加莱表面、周期轨道、吸引池和平衡点的稳定性。

Motion Properties in the GPCR3BP with Their Interactions under the Effects of Variable Mass and Asteroids Belt

Motion Properties in the GPCR3BP with Their Interactions under the Effects of Variable Mass and Asteroids Belt

The main aim of this paper is to investigate numerically the dynamical motion properties of the infinitesimal body under the various types of perturbations in generalized perturbed circular restricted three-body problem (GPCR3BP). Out of three bodies, one bigger body (known as primary) is taken as oblate in shape with radiation effects, another bigger body (known as secondary) is taken as triaxial in shape with albedo effect and the third body (known as infinitesimal body which is more smaller that the other two bigger bodies) is varying its mass. And also the perturbations due to asteroids belt, interactions between the bodies and the effects of Coriolis as well as centrifugal forces are assumed. Both primaries are moving in circular orbits around the origin which is their common center of mass also. Using the above defined perturbations, we determine the equations of motion and quasi-Jacobian integral for the infinitesimal body. We numerically perform the locations of equilibrium points (in-plane and out-of-plane), regions of motion, Poincaré surfaces of section, periodic orbits, basins of attraction and the stability of the equilibrium points.
