高偏心率和倾角下的冻结轨道:在水星轨道器上的应用

Frozen Orbits at high eccentricity and inclination: Application to Mercury orbiter

N. Delsate, P. Robutel, A. Lemaitre, T. Carletti

摘要:

本文利用Hamilton形式研究了无质量探测器绕一个扁圆中心体(行星或行星卫星)的稳定性,该中心体受第三体(例如太阳或木星)的扰动。我们能够确定,在参数空间中,冻结轨道的位置,即轨道的轨道要素保持不变的平均,以表征其稳定性/不稳定性,并计算平衡的周期。所提出的理论是足够普遍的,适用于广泛的探测器周围的行星或天然行星卫星。BepiColombo任务用于激励我们的分析,并提供具体的数值数据来检查我们的分析结果。最后,我们还指出,系数J_2可以防止Kozai-Lidov效应引起的偏心率的增加。

英文摘要:

We hereby study the stability of a massless probe orbiting around an oblate central body (planet or planetary satellite) perturbed by a third body, assumed to lie in the equatorial plane (Sun or Jupiter for example) using an Hamiltonian formalism. We are able to determine, in the parameters space, the location of the frozen orbits, namely orbits whose orbital elements remain constant on average, to characterize their stability/unstability and to compute the periods of the equilibria. The proposed theory is general enough, to be applied to a wide range of probes around planet or natural planetary satellites. The BepiColombo mission is used to motivate our analysis and to provide specific numerical data to check our analytical results. Finally, we also bring to the light that the coefficient J_2 is able to protect against the increasing of the eccentricity due to the Kozai-Lidov effect.
