Top: actual birth radii versus final radii for stars in different age bins as indicated in each panel. The dotted-red and solid-blue vertical lines indicate the positions of the bar’s CR and OLR. The dashed black line shows the locus of non-migrating circular orbits. Bottom: guiding birth radii versus guiding final radii. Using the guiding radii excludes the effect of high-eccentricity stars, thus exhibiting better the resonant locations as clumps along the dashed black line. The effect of the bar is seen in the overdensity inside the CR, indicating stars shifted preferentially from their radius outward in the disk. This becomes more evident for younger stars because of their colder orbits, allowing them to respond more strongly to the perturbations.
