Abstract In the Nice Model (Tsiganis et al, 2005) there is a consensus that the regular satellites are primordial and resisted the migration, while the irregular ones were captured a posteriori or during the migration. Although this never was tested in a rigorous way, in Deienno (2010), Deienno et al (2010), this problem was exaustively studied in the case of Uranus system. What is observed is that: from qualitative and statiscal point of view that is true, however the final resulting values of the eccentricity and inclination of the regular satellites are difficult to explain when compared to the current values. In this proposal, one studies some post Migration mechanism, such that the inclination and eccentricity could be damped to the current values as seen today. Additionaly, a similar and comparative investigation will be extended to Saturn system (already in progress). The study of the capture of the irregular satellites is an important point to be considered in this proposal. | |
