The apsidal antialignment of the HD 82943 system
Ji, JH; Kinoshita, H; Liu, L; Li, GY; Nakai, H
AbstractWe 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 (MMR) 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 theta(3) librates about 180degrees in the simulations. We also use a semi-analytical model to explain the numerical results for the system under study.
