Extended Data Fig. 7: Isotopic compositions of presolar grains in Bennu samples which reflect their stellar origins.
From: The variety and origin of materials accreted by Bennu’s parent asteroid
(a) O isotopic compositions of presolar silicates and oxides and (b) C and N isotopic compositions of Bennu presolar SiC (this study and2) compared to the literature138,139. Error bars (1-sigma) are only shown for the O-rich presolar grains in Bennu for clarity. Errors can be found in Supplementary Table 11.
