Comparison of subgrain Zr data to born-again AGB star and RAWD models. Zirconium isotopic ratios vs. atomic masses of Zr isotopes for subgrains measured in grains with 96Zr-excesses are shown with colored lines in panels a and b, respectively. Zirconium isotopic ratios from born-again AGB Sakurai’s Object (Herwig et al. 2011) and RAWD-B (Denissenkov et al. 2017) are plotted as grey dotted lines in the left and right column respectively. Results from four different decay times are shown with different markers as indicated in the legend. Grey dashed line represent the solar values. All errors show 1σ variation.
