enfatizaremos o efeito da obliquidade de Saturno na din{\^a}mica

Neste projeto tamb{\'e}m estuda-se alguns processos p{\'o}s
migra{\c{c}}{\~a}o do Modelo de Nice que possibilitariam o
decaimento das inclina{\c{c}}{\~o}es e das excentricidade de
forma a reproduzir os valores reais de hoje (dado que, como dito
acima, no mestrado encontramos configura{\c{c}}{\~o}es p{\'o}s
migra{\c{c}}{\~a}o muito diferentes das atuais). ABSTRACT: In
the Nice model is accepted that the regular satellites resisted to
planetary migration and the irregulars were captured during the
instability phase of the Solar System. Such problem was
exhaustively studied by us, in particular to the system of Uranus
(equatorial satellites). Was observed that, qualitatively and
statistically, it verifies. However, the resulting configuration
after the migration presents inclinations and eccentricities hard
to be explained if compared with the current observed values of
the regular satellites. In this project, we continue the study
done in Uranus, but now, considering that the satellites could be
formed on the local Laplace plane, not the equator. At the same
time, will be also done the extension to planet Saturn, attempting
to a comparative study of the systems of Uranus and Saturn. Recent
works suggest that the obliquity of Saturn is not primordial. So,
we will emphasize the effect of Saturns obliquity on the dynamics
of its satellites as well (specially Titan, Hyperion, and
Iapetus). Still in this project, we study some of the post
migrational process of the Nice model that would make possible the
decai of the orbital inclinations and eccentricities, in a such
way to reproduce the current values.",
