Stellar Radial Migration In Discs: A Quantification Of Churning And Blurring

Radial stellar migration in galactic discs has received much attention in studies of galactic dynamics and chemical evolution, but remains a dynamical phenomenon that needs to be fully quantified. We present results from Halle et al 2015 and extensions on the churning (change in angular momentum) and blurring (radial epicyclic oscillations) in simulations of bar-dominated discs, and we discuss the influence of radial migration on the dynamical heating of stellar discs.
