LA RECHERCHE A L'IMCCE

The research activities carried out at IMCCE concern as well theoretical part as applied part of celestial mechanics. The study of the dynamical systems, researches in Mathematics, space astrometry, ground-based astrometry of the objects of the Solar System and their applications to planetology, are the main scientific interests of the laboratory.

The scientific objectives of IMCCE are globally, to improve our knowledge of the planetary motions and of the structure and evolution of the gravitational systems. The involved celestial bodies are all the Solar System bodies, from the small ones such as the meteoroids, to the biggest ones such as the big planets. Several means as well theoretical ones (celestial mechanics, physics, mathematics,...) as practical ones (campaigns of observation, astrometric methods,...) are involved.

Specific efforts are carried out in order to develop dynamical models of high accuracy for the planets and the natural satellites. These models are applied in particular to the interpretation of space observations. Several extended activities are recently been performed in new domains such as the use of high angular resolution to study multiple asteroids, the study of extrasolar planets, or the study of the Oort cloud and the long period comets. Several discoveries have been done and new results have been obtained.
