倾斜海王星特洛伊的动力学研究
On the Dynamics of Inclined Neptune's Trojans
摘要:
研究了海王星类特洛伊轨道上人造小行星的动力学问题。通过在(a,i)平面上构造动力学映射,描述了轨道稳定性对初始半长轴a和倾角i的依赖关系.动力学图揭示了丰富的细节,特别是确定了i=45度处的不稳定能隙,并指出了该区域触发混沌的机制。我们的调查可以用来指导观察。
英文摘要:
The dynamics of artificial asteroids on the Trojan-like orbits around Neptune is investigated in this paper. We describe the dependence of the orbital stability on the initial semimajor axis a and inclination i by constructing a dynamical map on the (a,i)-plane. Rich details are revealed in the dynamical map, especially a unstable gap at i=45 deg is determined and the mechanism triggering chaos in this region is figured out. Our investigation can be used to guide the observations.
