Microscale Hydrogen, Carbon, and Nitrogen Isotopic Diversity of Organic Matter in Asteroid Ryugu
Larry R Nittler, Jens Barosch, Katherine Burgess +57
We report the H, C, and N isotopic compositions of microscale (0.2 to 2m) organic matter in samples of asteroid Ryugu and the Orgueil CI carbonaceous chondrite. Three regolith p…
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…
A dual origin for water in carbonaceous asteroids revealed by CM chondrites
Laurette Piani, Hisayoshi Yurimoto, Laurent Remusat
Carbonaceous asteroids represent the principal source of water in the inner Solar System and might correspond to the main contributors for the delivery of water to Earth. Hydrogen…
Micron-scale D/H heterogeneity in chondrite matrices: a signature of the pristine solar system water?
Laurette Piani, François Robert, Laurent Remusat
Organic matter and hydrous silicates are intimately mixed in the matrix of chondrites and in-situ determination of their individual D/H ratios is therefore challenging. Nevertheles…
