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 efficiently than prograde resonances. The project consists in simulations of capture in the coorbital resonance assisted by dissipative forces and their evolution including planetary perturbations. The main purpose is to identify typical capture paths as function of the orbital parameters and the stability of these configurations with respect to planetary perturbations. This will allow a better understanding of the more likely configurations to detect in planetary system, as well as giving clues on their origin.
