• Abstract

  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 in…

  Planetary formation and dynamics: from the Solar System to exoplanets, AP.JP

• Abstract

  Planet formation starts in a gaseous disk rotating around the young star called protoplanetary disk. Hydrodynamical simulations are commonly used to study the early stages of planet formation, as the dynamics of planets growing in gaseous disks. Planets gravitationally interact with the gas disk and migrate, typically inwards. In this research plan we will use hydrodynamical and/or N-body…

  Planetary dynamics in a gaseous disk, BP.IC

• 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 forma…

  Fragmentation effects on planet formation, BP.MS

• Abstract

  The main goal of this project is to contribute to the formation of an undergraduate student through a theoretical and numerical approach of the gravitational N-body problem, including also non-gravitational effects as gas drag and solar radiation pressure. The N-body problem, in particular for N=3 can be applied to several problems in planetary dynamics and spatial engineering. For instan…
