Image Details
Caption: Figure 10.
The largest panel on the top right shows the median mono-Rb tracks in [α/M]-[Fe/H] space, similar to what is done in Figure 9. The smaller panels show the density and median abundances for stars in different Rb bins, increasing from the top left (inner galaxy) to the bottom right (outer galaxy). The white lines and points mark the SF enhancements taken from P. Massana et al. (2022).
