Extended Data Fig. 4: Abundances and isotopic composition of C and N in Bennu samples (OREX-803058-0 and OREX-803059-0) compared to other carbonaceous astromaterials.
From: The variety and origin of materials accreted by Bennu’s parent asteroid
Summed abundance and isotopic composition of (a) carbon and (b) nitrogen obtained by stepped combustion of Bennu samples compared to carbon-rich carbonaceous chondrites. All data are from the OU laboratory, apart from Ryugu (open red diamonds18,109,110) and other Bennu data (open blue diamonds2) (Supplementary Table 5). Error bars on isotopic composition represent 2 SD and are smaller than the symbol.
