Azimuthal metallicity variations, spiral structure, and the failure of radial actions based on assuming axisymmetry

Victor P. Debattista, Tigran Khachaturyants, Joao A. S. Amarante +3

We study azimuthal variations in the mean stellar metallicity, <[Fe/H]>, in a self-consistent, isolated simulation in which all stars form out of gas. We find <[Fe/H]> variations c…
