小质量比空间限制三体问题的稳定性和二次共振

Stability and secondary resonances in the spatial restricted three-body problem for small mass ratios

Richard Schwarz, Akos Bazso, Balint Erdi, Barbara Funk

摘要:

本文研究了中等质量比(μ)(μ小于0.0045)下空间限制三体问题的二次共振和拉格朗日点L4的稳定性。然而,我们集中我们的调查小质量比μ小于0.001,这代表的质量比稳定配置的蝌蚪轨道在太阳系。通过数值方法研究了系统的稳定性,计算了不同参数平面上的稳定性图。我们开始研究次级天体的质量,从地球质量的天体到1000亿质量的天体。此外,我们改变了轨道要素(偏心率和倾角)的次级和特洛伊机构。对于这个参数空间,我们发现高阶二次共振,这是目前为各种倾角。为了确定二次共振,我们使用拉贝方程和频率分析。此外,我们研究了这些二次共振中和周围的稳定性。

英文摘要:

This paper is devoted to the study of secondary resonances and the stability of the Lagrangian point L4 in the spatial restricted three-body problem for moderate mass ratios (mu), meaning that mu is smaller than 0.0045. However, we concentrated our investigations on small mass ratios for mu smaller than 0.001, which represent the mass ratios for stable configurations of tadpole orbits in the Solar system. The stability is investigated by numerical methods, computing stability maps in different parameter planes. We started investigating the mass of the secondary; from Earth-mass bodies up to Jupiter-mass bodies. In addition we changed the orbital elements (eccentricity and inclination) of the secondary and Trojan body. For this parameter space we found high order secondary resonances, which are present for various inclinations. To determine secondary resonances we used Rabe's equation and the frequency analysis. In addition we investigated the stability in and around these secondary resonances.
