Radial mixing in galactic discs: the effects of disc structure and satellite bombardment

We use a suite of numerical simulations to investigate the mechanisms and effects of radial migration of stars in disc galaxies such as the Milky Way (MW). An isolated, collisionless stellar disc with an MW-like scaleheight shows only the radial 'blurring' expected of epicyclic orbits. Red...
