Absolute abundances of Au in the three RPA stars (pink, green and blue stars) and literature r-process-enriched stars included in Figure 5 (grey dots), as a function of stellar parameters T_eff (left panel), log g (middle panel), and [Fe/H] (right panel). In each panel, we also plot a least squares fit (grey line) and provide the Pearson correlation coefficient (r-value) and the corresponding probability of observing a correlation of at least this magnitude by chance (p-value). The abundances of Au seem to correlate with the stellar parameters, hinting at the presence of non-LTE effects.
