我们分析了来自Brasser & Morbidelli的详细的Nice模型模拟柯伊伯带的位置，其中海王星经历了一个高偏心率阶段并向外迁移。在这项工作中，在Pike等人的研究之后，我们特别关注海王星平均运动共振和模拟海王星外天体（TNOs）的高中心人口中的结构细节。我们发现了这些群体的几个特征，这些特征应该在未来的大规模TNO调查中在遥远的太阳系中观察到，以诊断这种海王星迁移模式是否发生在早期太阳系。我们发现n:1共振的前导非对称振动岛通常比后向岛屿的人口多得多。我们还发现，由于Kozai循环在其就位历史中的重要性，非共振高q群的TNOs应该比低q群具有更高的倾角。最后，高q TNOs应该以大致相等的数量出现在远端平均运动共振的两侧。这些预测与其他柯伊伯带就位模拟的预测形成对比，并将在即将进行的调查中得到验证。
We analyze a detailed Nice model simulation of Kuiper Belt emplacement from Brasser & Morbidelli, where Neptune undergoes a high-eccentricity phase and migrates outward. In this work, which follows from Pike et al., we specifically focus on the details of structures within Neptune’s mean-motion resonances and in the high-pericenter population of simulated trans-Neptunian objects (TNOs). We find several characteristics of these populations that should be observable in the distant solar system in future large-scale TNO surveys as a diagnostic of whether or not this mode of Neptune migration occurred in the early solar system. We find that the leading asymmetric libration islands of the n:1 resonances are generally much more populated than the trailing islands. We also find the nonresonant high-q population of TNOs should have higher inclinations than the low-q population due to the importance of Kozai cycling during their emplacement histories. Finally, high-q TNOs should be present in roughly equal numbers on either side of distant mean-motion resonances. These predictions contrast with predictions from other Kuiper Belt emplacement simulations and will be testable by upcoming surveys.
