Abstract

As a result of the different instruments on-board Gaia and their various spatial or time resolutions, millions of Double and Multiple Stars (DMS) will be detected, of almost every kind. Accordingly, the data processing of DMS will undoubtedly be complex. This processing can be described in broad categories: resolved doubles and multiple stars, astrometric, spectroscopic, photometric or eclipsing binaries and classification task; in total, not less than 32 algorithms may be needed, which also call for adapted simulations.
