摘要

摘要本文重新讨论了系外行星系统中环面存在的问题。具体来说,我们考虑υ Andromedæ系统,通过建模它与一个三体问题。这项初步研究使我们能够引入一种自然的方法来评估行星轨道的鲁棒性,这种方法可以很容易地在数值探索中实现。我们将我们的标准应用于选择合适的轨道配置的问题,该轨道配置具有很强的稳定性,并且与可用于υ Andromedæ系统本身的观测数据兼容。

A numerical criterion evaluating the robustness of planetary architectures; applications to the υ Andromedæ system
Abstract We revisit the problem of the existence of KAM tori in extrasolar planetary systems. Specifically, we consider the υ Andromedæ system, by modelling it with a three-body problem. This preliminary study allows us to introduce a natural way to evaluate the robustness of the planetary orbits, which can be very easily implemented in numerical explorations. We apply our criterion to the problem of the choice of a suitable orbital configuration which exhibits strong stability properties and is compatible with the observational data that are available for the υ Andromedæ system itself.
