Heavy-element abundance patterns of CS 22892-052 (filled rhombi) and benchmark r-II stars CS 31082-001, HE 1523-0901, and HE 1219-0312 (open triangles). The element abundances have been scaled to match Eu–Tm in CS 22892-052. The dashed and continuous curves indicate the SSr abundance patterns calculated using the s-process predictions of A99 and B14, respectively. The dotted curve corresponds to the HEW r-process model of Farouqi et al. (2010).
