Abstract The first planetary arcs were discovered in the 1980s on the Adams ring of Neptune. Similar structures has been discover on Saturn. The stability of these systems is usually attributed to resonances, as occurs with the arcs of Anthe, Methone and the G ring. These arcs is on Saturn and the searchers believes they are maintained by corotation resonances with Mimas. The stability of the Adams ring arcs has been attributed to the sum of a corotation resonance with a Lindblad resonance, both with the satellite Galatea. However, changes in the angular position and brightness of these arcs demonstrated that they could not be in resonance of corrotation. So, was proposed that the arcs would be maintained angularly by four coorbital satellites. Thus, the objective of this project is study the confinament of particles by corotation and Lindblad resonance. We will simulate numericaly a set of particles in diverse resonances with a fictitious satellite of variable mass and variables orbital parameters. All the resonant sites will be filled with particles, allowing the analysis of the orbital evolution of these sites under the effects of coorbital satellites. The results will be applied to the arcs of the Adams ring of Neptune and to the arcs of Anthe, Methone and the G ring of Saturn. (AU)’ | |
