Nakai (Purple Mountain Observatory, Nanjing Univ., NAOC, NAOJ | Abstract: | We perform numerical simulations to explore the dynamical evolution of the HD 82943 planetary system. By simulating diverse planetary configurations, we find two mechanisms of stabilizing the system: the 2:1 mean motion resonance between the two planets can act as the first mechanism for all stable orbits. The second mechanism is a dynamical antialignment of the apsidal lines of the orbiting planets, which implies that the difference of the periastron longitudes $ heta_{3}$ librates about $180^{circ}$ in the simulations. We also use a semi-analytical model to explain the numerical results for the system under study. | Source: | arXiv, astro-ph/0301353 | Services: | Forum | Review | PDF | Favorites |
