Title: Dynamical analysis of resonant multi-planet systems
Throughout this seminar, I intend to cover some of the general problems observed in the extrasolar population as a consequence of their dynamical evolution.
For this purpose, I will first present some planetary features and discuss in which context the planets were formed to obtain the currently observed architectures.
The focus will be on systems with 3-planets. The interest comes after the discovery of the TRAPPIST-1 system.
To carry out this investigation, we used N-body numerical simulations to study in detail the evolution of planetary systems during the early stages of planet formation, that is, when there was still gas in the protoplanetary disk. We make dynamical maps from grids of initial conditions for systems with planets of different masses and compare the results of the N-body simulations with the analytical modeling to understand the evolutionary paths, on which parameters of the disk depend, and other physical characteristics. We dynamically analyze the TRAPPIST-1 planetary system that lies in a very complex resonant configuration. Results are consistent with the fact that systems were not formed in-situ but had to migrate to reach their current positions, without having to suppose ad-hoc dissipative effects, such as tidal effects by the star.

Horizon Europe by ADRE (event in French)
2021-05-25 12:30 - 13:15
Le nouveau programme-cadre de l’Union européenne pour la recherche et l’innovation “Horizon Europe” a été lancé depuis janvier 2021. Il représente un budget de 95 milliard € qui seront investis dans la recherche pour la période allant de 2021 à 2027.
Nous (ADRE) pensons que ce programme est une opportunité pour mettre en évidences les compétences de l’Université de Namur, en particulier celles de l’institut NAXYS. Nous proposons donc de vous en donner un aperçu et parcourir ensemble quelques opportunités pour NAXYS.
Points abordés :

Enjeux majeurs et nouveautés par rapport à Horizon 2020

Taux de financement des activités pour les Universités et autres partenaires

Au-delà de l’excellence scientifique, les autres aspects à prendre en compte pour une proposition réussie

Quelles opportunités pour NAXYS ?

Support ADRE et incitants institutionnels

La réunion aura lieu sur Teams le mardi 25/05 de 12h30 à 13h15 et sera accessible via ce lien
