Computation of the Liapunov Orbits in the Photogravitational RTBP withOblateness

We study the periodic motion around the collinear equilibrium points of the restricted three-body problem when the primary is a source of radiation and the secondary is an oblate spheroid. In particular, the Liapunov families of two and three dimensional periodic orbits are computed. In order to gain the appropriate initial conditions a third-fourth order Lindstedt-Poincare local analysis is used. The stability of these families is also computed.
