Résumé
The orbits of extrasolar planets are more various than the circular and
coplanar ones of the Solar system. We study the impact of inclined and
eccentric massive giant planets on the terrestrial planet formation
process. The physical and orbital parameters of the giant planets
considered in this study arise from n-body simulations of three giant
planets in the late stage of the gas disc, under the combined action of
Type II migration and planet-planet scattering. At the dispersal of the
gas disc, the two- and three-planet systems interact then with an inner
disc of planetesimals and planetary embryos. We discuss the mass and
orbital parameters of the terrestrial planets formed by our simulations,
as well as their water content. We also investigate how the disc of
planetesimals and planetary embryos modifies the eccentric and inclined
orbits of the giant planets.
