Figure Lengend Snippet: a) The O isotopic compositions of presolar O‐rich grains identified in A12236 and A12169 are compared to literature data for presolar oxides and silicates in meteorites. The box indicates the plot range of (b). b) A zoomed‐in plot of the Asuka grain compositions overlaid on a probability density map of the literature in situ data. See text for details. The dashed lines indicate terrestrial (≈bulk meteorite) isotope ratios. Literature data are taken from a large number of sources (see e.g., Nittler et al. ; Nguyen et al. ; Leitner et al. ; Zinner ; Floss and Haenecour ).

Figure Lengend Snippet: Results of Monte Carlo modeling (Nittler et al. ) of presolar O‐rich grain abundances in A12169 and A12236. Two results are provided for A12169, one based on the 90 identified presolar grains in this meteorite and one (“A12169 exc. big”) that excludes the unusually large grain A12169‐23. The histograms indicate the distributions of abundances for 10,000 MC instances for each calculation, while circles and error bars indicate average abundances and ±1‐σ and 2‐σ error bars (84.1% and 97.7% enclosed probability).
