STXM-XANES and TEM analysis of UltraCarbonaceous Antarctic MicroMeteorites (UCAMMs)
B. Guérin, C. Engrand, C. Le Guillou +7
The Concordia micrometeorite collection contains UltraCarbonaceous Antarctic MicroMeteorites (UCAMMs) of probable cometary origin. Eight FIB sections of UCAMMs were studied by Scan…
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…
First MATISSE L-band observations of HD 179218. Is the inner 10 au region rich in carbon dust particles?
E. Kokoulina, A. Matter, B. Lopez +58
Carbon is one of the most abundant components in the Universe. While silicates have been the main focus of solid phase studies in protoplanetary discs (PPDs), little is known about…
