Astrométrie de haute précision et applications

The aim of the "action spécifique GRAM" (http://gram.oca.eu) is to develop and coordinate scientific activities between three themes:

High precision astrometry is naturally related to all three themes. The launch of GAIA planned for this year will allow unprecedented precision on many astronomical objects and will open the way to completely new applications. During this workshop we will emphasize the research concerning the theme of high precision astrometry whether related to GAIA or not. This will include observational and theoretical aspects, ongoing or planned projects, or applications taking advantage of the results of high precision astrometry. Meanwhile, this main theme does not exclude other contributions that more generally concern any of the scientific themes of GRAM.
