| Abstract: |
We carry out simulations to investigate the dynamical evolution of the GJ 876 and HD 82943 planetary systems consisting of two resonant Jupiter-like planets respectively, and reveal a possible stabilizing mechanism for maintaining the systems. By simulating and analyzing different coplanar and non-coplanar configurations, we find that all the stable cases are involved in the 2:1 mean motion resonance and that the alignment of the periastron of the two planets also plays an important part in the secular orbital evolution of the multi-planetary systems, indicating that the two kinds of mechanisms could be responsible for the dynamics of the two systems. |
