Abstract
Oxygen 3‐isotope ratios of magnetite and carbonates in aqueously altered carbonaceous chondrites provide important clues to understanding the evolution of the fluid in the asteroidal parent bodies. We conducted oxygen 3‐isotope analyses ...

We have conducted a NanoSIMS-based search for presolar material in samples
recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2
mission. We report the detection of all major presolar grain types with O- and
C-anomalous isotopic...
