A ring system detected around the Centaur (10199) Chariklo

We will report observations of a multichord stellar occultation that revealed the presence of a ring system around the centaur object (10199) Chariklo. There are two dense rings,with respective widths of about 7 and 3 kilometres, optical depths of 0.4 and 0.06, and orbital radii of 391 and 405 kilometres. We will also present more results obtained after the occultation on June 3rd 2013. Photometric and spectroscopic evidence can also explain the orientation of the ring plane, the presence of water ice on the rings and estimate the composition of the central body and the ring material.
