Abstract

A new class of system was discovered in the Saturn system, a close relation between small satellites and ring particles. The small satellites, Anthe, Methone, Pallene and Aegaoen are immersed in arcs or complete rings, mainly composed by tiny particles. In this project the orbital evolution of the small satellites, since they are in mean motion resonance with the satellite Mimas, under the gravitational effects of Mimas and Enceladus will be analysed through a sample of numerical simulations. The next part is related to the study of the particles and debris located in the arcs and rings under the effects of the satellites. This project can help to elucidate the formation of the arcs and their evolution. (AU)
