Quasi periodic coorbital motions (joint work with Philippe Robutel and Alexandre Pousse)

Abstract: The motions of the satellites Janus and Epimetheus around 

Saturn are among the most intriguing in the solar system since they 

exchange their orbits every four years.

We give a rigorous proof of the existence of quasi-periodic orbits of this 

kind in the three body planetary problem thanks to KAM theory.
