Orbit Determination for Gaia Spectroscopic Binaries

Synthetic radial velocities for a population of 2300+ known spectroscopic binaries are generated according to the present scanning law. The effect of the distribution of the observations and of the noise on the orbit fitting is investigated. According to our preliminary results short periods, below one day, will be hard to identify among the many aliases, even in the absence of noise. Requirements in terms of computing power for this shell task are estimated in conjunction with the adopted algorithm for the period search part of the orbit reconstruction. These results are for binaries detected in the Radial Velocity Spectrometer only.
