评价行星结构鲁棒性的数值准则;应用于$\upsilon$仙女座星系

A numerical criterion evaluating the robustness of planetary architectures; applications to the $\upsilon$ Andromedæ system

Ugo Locatelli, Chiara Caracciolo, Marco Sansottera, Mara Volpi

摘要:

我们重新讨论太阳系外行星系中KAM环面的存在问题。具体来说,我们认为$\upsilon$仙女座系统,通过建模它与三体问题。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,这可以很容易地在数值探索中实现。我们应用我们的标准选择一个合适的轨道配置,表现出很强的稳定性和兼容的观测数据,可用于$\upsilon$仙女座星系系统本身的问题。

英文摘要:

We revisit the problem of the existence of KAM tori in extrasolar planetary systems. Specifically, we consider the $\upsilon$ 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 $\upsilon$ Andromedæ system itself.
