【摘要】 对当前观测到的具有可靠轨道根数的共振Kuiper带天体的轨道未来演化进行数值模拟发现,它们的轨道在一亿年的时间演化中具有相对稳定性,即仍处于各自的共振区中,但稳定程度不同,且共振天体的轨道稳定性和其初始轨道半长径、偏心率和倾角有关.根据其轨道半长径、偏心率和倾角随时间的演化行为,这些共振天体可以分为具有"规则轨道"和"混沌轨道"两种类型.更多还原

【Abstract】 Orbital evolution of RKBOs is simulated by using reliable orbital elements over a timescale of 10~8 year.It shows that their orbits are relatively stable in resonant regions.Stability depends on initial orbital semi-major axis,eccentricities and inclinations of these resonant bodies.According to dynamical behavior of orbital semi-major axis,eccentricity and inclination,RKBOs are classified into regular or chaotic orbits.更多还原
