Th/Eu abundance ratios of the Roederer et al. (2009) sample, HE 2327−5642 (Paper V), CS 30315-029 (Siqueira-Mello et al. 2014), and HE 2252−4225 (filled rhomb inside open circle). Stars with high Th/Eu ratios (log(Th/Eu) ≥ −0.35) are shown by filled rhombi and the remaining stars with open rhombi. The horizontal lines indicate the ratios expected if a sample of material had a given age, assuming the solar r-process of Bisterzo2014.
