Pr. Sébastien Charnoz is a planetary scientist who studies planetary dynamics at the Université Paris 7, in Paris. He also works for the CEA in France. His work covers problems relating to collisional-dynamics such as the physics of planetary rings and the formation of the Solar System. He is a specialist of numerical simulations. Along with André Brahic he is involved in the imaging team of the Cassini mission, led by Carolyn Porco. Using a numerical code he wrote for an automatic satellite-detection, he helped the Imaging Team discover the two smallest known moons of the Saturn system in 2004,,,: Methone and Pallene.
