Upper panel: abundance pattern of HD 45184 (red filled circles) versus condensation temperature. We reproduce the chemical pattern of HD 45184 (blue filled triangles) adding 3.5 M_⊕ of Earth-like material to the convective zone of the Sun. Lower panel: the differential abundance ratios of Inti 1 (red filled circles) relative to the Sun as a function of condensation temperature. The mean abundance pattern of 11 solar twins studied by Meléndez et al. (2009) is represented by the black dashed line. We could reproduce the trend of Inti 1 (blue filled triangles), adding 1.5 M_⊕ of Earth-like material to the convective zone of the Sun. Neutron capture elements are represented by squares in both panels.
