Isotopic variation of non-carbonaceous meteorites caused by dust leakage across the Jovian gap in the solar nebula
Kazuaki A. Homma, Satoshi Okuzumi, Sota Arakawa +1
High-precision isotopic measurements of meteorites revealed that they are classified into non-carbonaceous (NC) and carbonaceous (CC) meteorites. One plausible scenario for achievi…
The Elemental Abundances of Ryugu: Assessment of Chemical Heterogeneities and the Nugget Effect
Tetsuya Yokoyama, Nicolas Dauphas, Ryota Fukai +6
The Hayabusa 2 spacecraft sampled ~5.4 g of asteroid material from the Cb-type asteroid Ryugu. Initial analysis of the Ryugu materials revealed a mineralogical, chemical, and isoto…
Mixing model of Phobos' bulk elemental composition for the determination of its origin: Multivariate analysis of MMX/MEGANE data
Kaori Hirata, Tomohiro Usui, Ryuki Hyodo +6
The formation process of the two Martian moons, Phobos and Deimos, is still debated with two main competing hypotheses: the capture of an asteroid or a giant impact onto Mars. In o…
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…
Assessment of Cr isotopic heterogeneities of volatile-rich asteroids based on multiple planet formation models
Ryota Fukai, Sota Arakawa
Describing the comprehensive evolutionary scenario for asteroids is key to explaining the various physical processes of the solar system. Bulk-scale carbonaceous chondrites (CCs) p…
