In this project, we use computational simulations to study the intermediate and late stages of planetary formation. This project essentially comes in two flavors. The first one is focused on studies of the accretion of terrestrial planets in the Solar System. The second is focused on studies of formation systems of close-in super-Earths around other stars. The nature of the simulations invoked in this project goes from pure N-body gravitational simulations to complex hydrodynamical simulations. The goals of this project is evaluate models of formation and evolution of the Solar System and exoplanetary systems. In the context of the Solar System, it is expected that the results from this proposal can bring a better understanding of how the terrestrial planets, giant planets, and the asteroid belt formed and evolved from a dynamical point of view. In the context of exoplanets, the results from this proposal will help to constraint and distinguish the dynamical processes that played the leading role for the formation of systems of close-in super-Earths, the known most common type of planets in the galaxy.
