论文摘要
在近二元电势中高分子轨道上的低质量物体的磁盘可以动态地不稳定，无法从平面上屈曲。在这封信中，我们介绍了$ n $ body模拟这种系统的长期行为，发现磁盘平面中轨道的apsidal聚类。粒子数量的数量增加了聚类的时间尺度，这表明偏斜的配置在大$ n $上是稳定的。该发现可能解释了外部太阳系中极端型河内对象的观察到的apsidal（$ \ varpi $）聚类。
Disks of low-mass bodies on high-eccentricity orbits in near-Keplerian potentials can be dynamically unstable to buckling out of the plane. In this letter, we present $N$-body simulations of the long-term behavior of such a system, finding apsidal clustering of the orbits in the disk plane. The timescale over which the clustering is maintained increases with number of particles, suggesting that lopsided configurations are stable at large $N$. This discovery may explain the observed apsidal ($\varpi$) clustering of extreme trans-Neptunian Objects in the outer solar system.
