Comparison of s-process nucleosynthesis results on the stellar surface of 3 M_⊙ models at solar metallicity of Monash, FRUITY, NuGrid, and SNUPPAT. From Monash, we selected the Z = 0.14 model with M_mix equal to 2 × 10⁻³ M_⊙ (Karakas 2014; Karakas & Lugaro 2016). From the FRUITY models, we selected the Z = 0.014 and Z = 0.02 models. From NuGrid, we chose the Z = 0.02 models from Battino et al. (2016), marked in the legend as ‘B16’, and Pignatari et al. (2016), marked in the legend with ‘P16’.
