长期四极三体问题中的高倾角轨道

High inclination orbits in the secular quadrupolar three-body problem

Francois Farago, Jacques Laskar

摘要:

Lidov-Kozai机制允许物体周期性地交换其偏心率与倾角。它最初是在四极长期限制性三体问题的框架下讨论的,其中无质量粒子是内部物体,后来扩展到四极长期非限制性三体问题。在本文中,我们提出了一个不同的观点的问题,首先在限制问题,无质量的粒子是外体。在这种情况下,出现了高互倾角的平衡,这对应于Verrier & Evans(2008,2009)在围绕四星HD 98800的一个组成部分的稳定,高倾角的环联星轨道上发现的稳定粒子群。我们提供了一个简单的分析框架,使用矢量形式主义这些情况。我们也看看在非限制性的情况下,这些高倾角平衡的演变。

英文摘要:

The Lidov-Kozai mechanism allows a body to periodically exchange its eccentricity with inclination. It was first discussed in the framework of the quadrupolar secular restricted three-body problem, where the massless particle is the inner body, and later extended to the quadrupolar secular nonrestricted three body problem. In this paper, we propose a different point of view on the problem by looking first at the restricted problem where the massless particle is the outer body. In this situation, equilibria at high mutual inclination appear, which correspond to the population of stable particles that Verrier & Evans (2008,2009) find in stable, high inclination circumbinary orbits around one of the components of the quadruple star HD 98800. We provide a simple analytical framework using a vectorial formalism for these situations. We also look at the evolution of these high inclination equilibria in the non restricted case.
