Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, Á. Planchuelo Gómez, E. Caffau, P. Bonifacio et autres
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down to a signal-to-noise ratio (S/N) of 2. In this very low S/N regime, noise-induced …
