Abstract

We conducted numerical simulations of 3,830 massless test particles in the Saturn system near the 7: 6 corotation eccentricity resonance (CER) with Mimas, in response to the recent observations of an arc in the faint and dusty G Ring (see Hedman et al, this conference). We simulated 80 years of evolution, taking into account the perturbations of Saturn s nine most massive moons, the Sun, Jupiter, and Saturn s J 2 and J 4 gravity harmonics. Perturber trajectories were obtained at every timestep from JPL ephemera ...
