Binaries in Gaia perspective. DR3 teaser
Abstract
The third Gaia data release (Gaia DR3) will be the first in which binary models will be considered in the processing of the positions, velocities, and fluxes. This will likely change the values available (based on the single star assumption) but will provide some additional parameters directly related to the binary nature of the source. The present status of the binary pipeline, based on a few thousand cases, is illustrated here for the very first time.
