The existence of asteroids like the coorbital 2015BZ509 and the transneptunians Niku and Drac whose orbits have high relative inclination with respect to the planets' orbital plane is problematic in the context of the current theories for formation and evolution of the solar system. The recent modelling and subsequent identification of orbital resonances with the giant planets was e...
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 sign...
Recently, the existence of retrograde coorbital configurations in the solar system has been confirmed: asteroid (514107) Ka'epaoka'awela that revolves around the sun in the same period as Jupiter but orbiting in the opposite direction. Simulations of the 3-body problem with dissipation showed that retrograde resonances, and particularly the coorbital resonance, capture objects more effi...
