Presolar O- and C-anomalous grains in unequilibrated ordinary chondrite matrices
Jens Barosch, Larry Nittler, Jianhua Wang +4
Presolar grains are trace components in chondrite matrices. Their abundances and compositions have been systematically studied in carbonaceous chondrites but rarely in situ in othe…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
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…
TEM analyses of in situ presolar grains from unequilibrated ordinary chondrite LL3.0 Semarkona
Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3
We investigated six presolar grains from very primitive regions of the matrix in the unequilibrated ordinary chondrite Semarkona with TEM. These grains include one SiC, one oxide (…
