Bruno Sicardy Biography

Sicardy helps identify occultation evidence for incomplete ring structures around Neptune.

Sicardy helps obtain further occultation evidence confirming that Neptune possesses persistent ring arcs.

Voyager images confirm that the earlier ground-based occultation events were produced by real ring arcs.

Adaptive-optics observations obtain direct ground-based images of Neptune's ring arcs.

Sicardy publishes ground-based adaptive-optics observations showing that Neptune's ring arcs remain dynamically complex.

Sicardy and colleagues observe Eris occulting a star, enabling a precise measurement showing its size is comparable to Pluto's.
