Abstract

The phase space structure around L4 in the restricted three-body problem is investigated. The connection between the long period family emanating from L4 and the very complex structure of the stability region is shown by using the method of Poincaré’s surface of section. The zero initial velocity stability region around L4 is determined by using a method based on the calculation of finite-time Lyapunov characteristic numbers. It is shown that the boundary of the stability region in the configuration space is formed by orbits suffering slow chaotic diffusion.
