Characteristics of natural remanence records in fine-grained particles returned from asteroid Ryugu
Masahiko Sato, Yuki Kimura, Tadahiro Hatakeyama +25
Particles collected from the asteroid Ryugu by the Hayabusa2 spacecraft offer a unique opportunity to investigate the magnetic record of the primitive solar system, as any terrestr…
The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites
Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88
The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…
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…
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…
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…
Revised phase diagram of the high- cuprate superconductor Pb-doped BiSrCaCuO revealed by anisotropic transport measurements
Keiichi Harada, Yuki Teramoto, Tomohiro Usui +9
Although phase diagrams can be leveraged to investigate high transition temperature (high-) superconductivity, the issue has not been discussed thoroughly. In this study, we e…
