[X/Fe] vs [Fe/H] for n-capture elements for models with increased MNS r-process production at low-metallicity (see Eq. (4)). Solid lines are genuine chemical evolution tracks for the reference models adopting Rubele et al. (2018) SFH (blue) and Massana et al. (2022) SFH (green), whereas shaded cyan and light-green regions are associated model predictions account for observational uncertainties ('synthetic models'). Data are as in Fig. 5.
