The planetary community, and in particular his French colleagues and friends, are very sad to announce the passing of Andre Brahic. Professor at the University Paris-Diderot, based at the Observatory of Paris until 1995 and the AIM laboratory at CEA Saclay, Andre Brahic
devoted most of his career to the study of solar system bodies, in particular of planetary rings and the formation of planets, but started out by working on the chaos theory, the dynamics of galaxies and the supernovas. He was a member of the scientific teams of the cameras on
Voyager 1 and 2, through which he made many discoveries and notably confirmed the existence of Neptune rings and the arcs of the Adams ring, that he had predicted. With an international team, he showed that the Adams ring, is actually composed of four arcs that he and his collaborators baptized “Courage”, “Liberte”, “Egalite”, “Fraternite” (CLEF for “KEY” in French). He was also a [Cassini science team member] … Andre Brahic was of course also an extraordinary communicator, who transmitted his passion for science and astrophysics
to generations of students and to the public.
