First evidence of the deformation of Saturn by tidal effects

Using several thousand images of Saturn's moons produced by the Cassini probe (NASA/ESA), an international team led by an astronomer from the Observatoire de Paris in the Institute of Celestial Mechanics and Calculation of Ephemerides ( Observatoire de Paris / CNRS / UPMC / Université Lille 1), in collaboration with CEA researchers, has succeeded in bringing to light small fluctuations in the gravitational field of the planet. These extremely fine results are the outcome of a series of works carried out by the same team on the Saturn ecosystem and should allow to better understand the internal structure of Saturn. These results are in press in the International Journal Icarus and are the subject of an video.
