论文摘要
观察到的小体轨道（TNOS）中小体轨道的物理聚类最近促使外部太阳系中额外的行星预测。自从假设的最初摆姿势以来，九行星对TNOS主簇的动力学的影响 - 与其轨道抗结队的对象 - 已得到充分研究。特别是，数值模拟揭示了一种引人入胜的现象，称为“共振跳跃”，其中这些对象突然在不同的平均动力相互抗性与第九行星之间过渡。在这项工作中，我们更详细地探讨了这种效果，目的是了解哪种机制促使跳跃事件发生。在此过程中，我们阐明了海王星散射相互作用的经常被低估的作用，这导致在这些远处的TNO的半大轴中扩散。此外，我们证明，尽管确实发生了一些与行星的共振相互作用，但反对准的物体能够在没有共振的情况下生存，证明TNOS的动力学主要由世俗的，而不是共振，而不是与行星九的互动。
The observed physical clustering of the orbits of small bodies in the distant Kuiper Belt (TNOs) has recently prompted the prediction of an additional planet in the outer solar system. Since the initial posing of the hypothesis, the effects of Planet Nine on the dynamics of the main cluster of TNOs - the objects anti-aligned with its orbit - have been well-studied. In particular, numerical simulations have revealed a fascinating phenomenon, referred to as "resonance hopping", in which these objects abruptly transition between different mean-motion commensurabilities with Planet Nine. In this work, we explore this effect in greater detail, with the goal of understanding what mechanism prompts the hopping events to occur. In the process, we elucidate the often underestimated role of Neptune scattering interactions, which leads to diffusion in the semi-major axes of these distant TNOs. In addition, we demonstrate that although some resonant interactions with Planet Nine do occur, the anti-aligned objects are able to survive without the resonances, confirming that the dynamics of the TNOs are predominantly driven by secular, rather than resonant, interactions with Planet Nine.
