SUMMARY:Manu Stalport (Geneva University\, Switzerland)
DESCRIPTION:Title: A calibration of chaos for the refinement of planetary systems \nAbstract: The observed diversity of planetary systems raises questions that challenge the formation and evolution models. A precise knowledge of the systems architectures is key in order to identify the leading processes shaping them. In this presentation\, I will discuss on how the study of chaos can provide a more precise view of the planetary systems. A particular interest is drawn on a numerical chaos indicator\, namely the Numerical Analysis of Fundamental Frequencies (NAFF\, J. Laskar)\, and its link with orbital instability. Combining the lessons learned together with a Bayesian exploration of the parameter space\, we design a technique used to refine the planet parameters. I will illustrate this approach on a few notable planetary systems.  \nThe seminar will take place in room S09 at the Faculty of Sciences
