Fractional changes in σz(r) and σr(r) resulting from the migrated stars. The dashed black curve plots the quantity , where σz,all and are the vertical velocity dispersions obtained from the total population and the non-migrators, respectively. A similar expression estimates Δσr, shown by the solid orange curve. The dotted-red and solid-blue vertical lines denote the bar’s CR and OLR, corresponding to the final time shown in each time period. Note the inverse correlation between Δσz and Δσr, indicating coupling between the radial and vertical motions of stars.
