Abstract

For simplicity, most planet formation models assume that collisions during the intermediate and final phases of planetary formation are constructive. This type of approach has been used both in solar system and exoplanet formation models. The objective of this master's thesis project is to study the impact of a more realistic collision treatment in numerical simulations modeling the formation of planetary systems, in particular the formation of hot super-Earth systems. We will incorporate into Mercury an algorithm for solving collisions calibrated from impact results of hydrodynamic and high-resolution N-body simulations. The results obtained here will be compared with those in the literature where the effects of fragmentation are simply neglected and also confronted with observational data. (AU)
