Birth radii distributions of the mono-age MW disk stars currently located within 0.25 dex of different radii (as indicated by the dashed black line in each panel) with |z| ≤ 0.5 kpc. The area under each mono-age curve is normalized to 1, so the curves are not representative of the relative proportion of each age at a given radii, but rather to illustrate the individual trends of each mono-age population. For each radial bin, the youngest population peaks within 0.5 kpc from where they are currently located today while each older population has consecutively smaller and smaller birth radii. Comparing the distribution of stars in the solar neighborhood (bottom left panel) to that of Ratcliffe et al. (2023), the correction used in this paper provides less migration for the 2–6 Gyr old populations and less spread in the oldest population.
