Whiting 1: Confirmation of its accretion by the Milky Way

Whiting 1: Confirmation of its accretion by the Milky Way

We investigate the association of Whiting 1 with the Sagittarius tidal stream by obtaining radial velocities for a sample of 101 stars observed with VIMOS. Our results reveal the presence of a component of the Sagittarius tidal stream with a radial velocity – and distance – compatible with that of t...
