• Research Activities of the group (click here for some previous results in french ...)

Research Topic: Formation and evolution of Planetary Systems

• Formation of planetesimals in proto-planetary disks
• Planetary migration in disks
• Collisional physics between small bodies
• Small body dynamics in the Solar System
• Evolution and internal struture of telluric and giant planets, and brown dwarfs
• Evolution of extra-solar planetary systems
• Development of matehmatical methods and tools: dynamical system analysis
• Observations of small bodies with large instruments (ESO, CFHT)

Movies of simulations used in the presentation:

1. Simulation of evolution of'asteroids injected in the resonance nu6 (size: 48.4 Mo)
2. Simulation of collision between asteroids (size: 4.2 Mo)
3. Simulation of dynamical evolution of membres of the Koronis family including the thermal force Yarkovsky (size: 4.5 Mo)
