Resumo

In a previous work, Giuliatti Winter et al. found several stable regions for test particles in orbit around Pluto associated with families of periodic orbits obtained in the circular, restricted three-body problem. They have shown that a possible eccentricity of the Pluto-Charon binary slightly reduces but does not destroy any of these stable regions. In this work, we extended their results by analysing the cases with the orbital inclination (I) equal to zero and considering the argument of pericentre (omega) equal to 90 degrees, 180 degrees and 270 degrees. We explore the influence of the orbital inclination of the particles in these stable regions. In this case, the initial inclination varies from 10 degrees to 170 degrees in steps of 10 degrees. We also present a sample of results for the longitude of the ascending node Omega = 90 degrees, considering the cases I = 20 degrees, 50 degrees, 130 degrees and 180 degrees. Our results show that stable regions are present in all of the inclined cases, except when the initial inclination of the particles is equal to 110 degrees. A sample of 3D trajectories of quasi-periodic orbits were found related to the periodic orbits obtained in the planar case by Giuliatti Winter et al. (AU)
