Comparison of the r-process abundances from neutron star mergers with those observed in r-process-enhanced metal-poor stars. Eight r-process-enhanced metal-poor stars are considered: CS 31082–001 (Hill et al. 2002), BD +17°3248 (Cowan et al. 2002), HE 1523–0901 (Frebel et al. 2007), CS 29497–004 (Hill et al. 2017), J2038–0023 (Placco et al. 2017), J0954+5246 (Holmbeck et al. 2018), J2003–1142 (Yong et al. 2021), and J2213–5137 (Roederer et al. 2024). The element abundances of these stars are scaled to Y(Z = 63) = 5.0 × 10⁻⁵. The blue lines represent the average abundances across the astrophysical models for neutron star mergers.
