Abstract

Extrasolar planetary systems are being discovered at a fast pace, often in dynamical configurations very different from our Solar System. Motivated by these recent discoveries we propose to continue a study on several topics: 1) the dynamics of non-coplanar systems with relative inclination ranging between 0 to 180 degrees ; 2) hierarchical systems and associated radial velocity signal; 3) stability of planets around binary systems. As a side project designed to engage computer science students at the host institution we will apply machine learning tools to extract knowledge from asteroid data. (AU)
