CAUSTICS OF THE RESTRICTED 3-BODY PROBLEM

Trajectories of the planar, circular, restricted three-body problem ar e given in the configuration space through the caustics associated to the invariant tori of quasi-periodic orbits. It is shown that the caus tics of trajectories librating in any particular resonance display som e features associated to that resonance. This method can be considered complementary to the Poincare surface of section method, because it p rovides information not accessible by the other method.
