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

Ugo Locatelli, Chiara Caracciolo, Marco Sansottera +1

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 pr…
