Figure 9. — Patterns of neutron-capture elements in the target stars with [Ba/Eu] > −0.6. All stars are shifted to a common Eu abundance. The top left panel shows stars with signs of s-process contamination, based on high Ba, La, Ce, etc. The top right panel shows stars with high [Ba/Eu], but an ambiguous pattern. The bottom two panels show stars with [Ba/Eu] > −0.5 (left) and −0.6 < [Ba/Eu] < −0.5 (right) but where all elements other than Ba are consistent with the pattern in 2792.
