[Eu/Fe] over [Fe/H] for the Z06-star (magenta star) and the J13-star (teal diamond). For reference, we plot the bulge (magenta circles) and disc stars (grey squares) from Forsberg et al. (2019) as well as the bulge stars from Johnson et al. (2012). The abundances of the halo stars come from the r-process alliance sample (dark grey triangles Holmbeck et al. 2020). The orange line indicates the ‘r-II’ limit as defined in the r-process alliance (Holmbeck et al. 2020). We note that the abundances from Forsberg et al. (2019) have been systematically lowered with 0.10 dex, as described in Sect. 3.1.
