Overview of the observed [Pb/hs] (upper panel) and [Pb/ls] (lower panel) upper limits of s-process enriched post-AGB stars in the Magellanic Clouds from this study and De Smedt et al. (2014). The observed abundance upper limits are plotted together with the [Pb/hs] and [Pb/ls] predictions of the 2.0 M_⊙ STAREVOL models (red full line),the 2.0 M_⊙ and 2.1 M_⊙ Mount Stromlo models (black crosses and yellow diamond, respectively) and the 1.5 and 2.0 M_⊙ FRUITY models (green dashed and blue dot-dashed lines, respectively). The black horizontal lines represent the [Fe/H] uncertainty of the stars shown. The position of each star is indicated with the first part of its 2MASS name. For more information, see text.
