摘要：

The four main scientific objectives of PRIMA - the Phase-Referenced Imaging and Microarcsecond Astrometry facility for the VLTI - will be described: - extra-solar system characterization with astrometry, to detect planets and evaluate their mass, and imaging of the dust accretion disk, - galactic center study with astrometry( dynamics of the bulge stars) and imaging at 10 mum ( piercing the gas and dust clouds surrounding the galactic center), - observations of AGNs and other extra-galactic objects, too faint to be observed without PRIMA, for which partial imaging is needed to constrain their structure models, - micro-gravitational lensing event resolution ( imaging and astrometry of their photo-center) in the Galactic Bulge and Magellanic Clouds, helping to determine directly the lens mass and distance.
