The Pristine survey. XXVI. Chemical abundances of subgiant stars of the extremelymetal-poor stream C-19
P. Bonifacio, E. Caffau, P. François +17
Context: The C-19 stellar stream is the most metal-poor stream known to date. While its width and velocity dispersion indicate a dwarf galaxy origin, its metallicity spread and abu…

Capture of field stars by dark substructures
Jorge Peñarrubia, Raphaël Errani, Matthew G. Walker +2
We use analytical and -body methods to study the capture of field stars by gravitating substructures moving across a galactic environment. The majority of stars captured by a su…

Collisionless relaxation from near equilibrium configurations: Linear theory and application to tidal stripping
Simon Rozier, Raphaël Errani
Placed slightly out of dynamical equilibrium, an isolated stellar system quickly returns towards a steady virialized state. We study this process of collisionless relaxation using…
