圆轨道、李雅普诺夫稳定性和Manev型力

Circular orbits, Lyapunov stability and Manev-type forces

Cristina Blaga

摘要:

本文研究了广义Manev两体问题中圆轨道在李雅普诺夫意义下的稳定性。首先,我们探讨了圆轨道的存在性,并确定了它们的半径。然后,使用第一运动积分,我们建立一个正定函数,称为李雅普诺夫函数。它的存在性证明了圆轨道在李雅普诺夫意义下是稳定的。最后,我们考虑了几个实际的两体系统,比较了牛顿引力场和修正的Manev引力场引力场中的圆轨道的特征,讨论了观测两种引力场中运动差异的可能性。

英文摘要:

In this article we study the stability in the sense of Lyapunov of the circular orbits in the generalized Manev two bodies problem. First, we explore the existence of the circular orbits and determine their radius. Then, using the first integrals of motion we build a positive definite function, known as a Lyapunov function. It's existence proves that the circular orbit is stable in the sense of Lyapunov. In the end, we consider several real systems of two bodies and compare the characteristics of the circular orbits in Newtonian and modified Manev gravitational field, arguing about our possibilities to observe the differences between the motion in these two fields.
