Census of binaries - The big picture

Söderhjelm, Staffan LU (2005) Symposium - The Three-Dimensional Universe with Gaia In European Space Agency, (Special Publication) ESA SP 576. p.97-104
Abstract
Gaia will observe huge numbers of binaries with a large range of periods. The present contribution tries to present some estimates of the expected number of detections and/or orbit determinations, based on simplified but large-scale simulations. The simulations have to model both a Galaxy with binaries, the instrument and observations, and the reduction programs. As in previous studies, there are marked distance-effects, with the solar neighbourhood (within a few hundred pc) much more completely sampled than more typical (few kpc) Gaia distances. The large number of simulated solutions allows also a study of some systematic effects in the astrometry of undetected binaries.
