A reinterpretation of the Triangulum–Andromeda stellar clouds: a population of halo stars kicked out of the Galactic disc

The Triangulum–Andromeda stellar clouds (TriAnd1 and TriAnd2) are a pair of concentric ring- or shell-like overdensities at large R (≈30 kpc) and Z (≈−10 kpc) in the Galactic halo that are thought to have been formed from the accretion and disruption of a satellite galaxy.
