Abundance ratios in r- II (circles), r- I (triangles) stars, and sample stars with normal [Eu/Fe] < −0.3 (squares). Smaller symbols represent stars with [Fe/H] > −2.5. An x symbol indicates a pure r-process ratio derived from average abundances in r- II sample stars. Different lines show abundance ratios calculated for mixtures of r-process and s-process with varying [Sr/Ba]earlyS. See the legend for designations.
