HSTPROMO Internal Proper Motion Kinematics of Dwarf Spheroidal Galaxies: I. Velocity Anisotropy and Dark Matter Cusp Slope of Draco

Eduardo Vitral, Roeland P. van der Marel, Sangmo Tony Sohn +8

We analyze four epochs of HST imaging over 18 years for the Draco dwarf spheroidal galaxy. We measure precise proper motions (PMs) for hundreds of stars and combine these with exis…

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…
