Caption: Figure 10.

Upper panel: heavy-element chemical abundance pattern of RAVE J1830−4555 (see text for explanations of the choices for the Pb and Th values—upper limits also shown for reference), compared with the r-process nucleosynthesis yields for two very fast (﹩v\gt 0.5c﹩) example tracers 0032 and 2131 from a simulation of a neutron star merger (Bovard et al. 2017). The abundance pattern is scaled to match the observed abundance of Ce. Lower panel: residuals between observations and the scaled abundance patterns of fast r-process ejecta.
