Radial profiles of A(Li), [Fe/H], [α/H], and [O/H] in the galactic gas of our model. Different solid lines show the profiles at different ages (lookback times) and have colours according to their age. The five-pointed stars show the position and abundances of open clusters according to Romano et al. (2021), with age colour-coded. For Berkeley 73 and NGC 2158, we show additional [Fe/H] estimations from Netopil et al. (2016) with smaller five-pointed stars. The grey dashed lines show the solar birth radius and abundances, while the solar symbol shows the present-day location.
