Dynamical astronomy, cosmology and astrobiology

astro

This research pole deals with the modelling of the Universe, on different scales: space debris, Solar System, extrasolar systems, up to the large-scale structures of the Universe. We will focus on the non-linear interactions and chaotic dynamics of these physical and mathematical objects, sharing the tools of celestial mechanics, cosmology, general relativity and modified gravity.

Keywords: Celestial Mechanics, Extrasolar Planets, Cosmology, Numerical Relativity, Astronomy
