Ba/Eu abundance ratios of r-II (filled circles), r-I (open rhombi), and Eu-poor (asterisks) stars (for the sources of the data, see text). The error bars were computed as where the abundance errors were available. The continuous and long-dashed lines indicate the SSr ratios, as predicted by GCE calculations of Bisterzo et al. (2014) and Travaglio et al. (1999), respectively, while the short-dashed and dash-dotted lines correspond to the SSr of Arlandini et al. (1999) and Bisterzo et al. (2011), respectively. The dotted line corresponds to the SS ratio (Lodders et al. 2009).
