1. Transferências orbitais e dinâmicas na vizinhança dos pontos lagrangianos L1 e L2 / Transfer orbits and dynamics around the lagrangian points L1 e L2
In this work we present a study of the dynamics in the vicinity of the Lagrangian points L1 and L2 in the restricted three-body problem, considering the Sun-Earth and Earth-Moon models. Notwithstanding the hyperbolic character of these points, the reduction to the central manifold allows periodic and quasi-periodic orbits. This procedure is applied through t

2. Transferência orbitais envolvendo órbitas do tipo halo / Transfers involving orbits of type halo
In space activities, it is of great importance the study of trajectories that the space vehicles should follow to complete a mission. In the present work, maneuvers involving Halo orbits for several systems of primary are studied. To accomplish this study the method of Lindstedt-Poincaré is used for the etermination of the orbits and the method of Lambert i
