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…

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…

The spatial distribution of impact craters on Ryugu

Naoyuki Hirata, Tomokatsu Morota, Yuichiro Cho +40

Asteroid 162173 Ryugu has numerous craters. The initial measurement of impact craters on Ryugu, by Sugita et al. (2019), is based on Hayabusa2 ONC images obtained during the first…

Rotational effect as the possible cause of the east-west asymmetric crater rims on Ryugu observed by LIDAR data

Naoyuki Hirata, Noriyuki Namiki, Fumi Yoshida +13

Asteroid 162173 Ryugu is a rubble-pile asteroid, whose top-shape is compatible with models of deformation by spin up. Rims of major craters on Ryugu have an east-west asymmetric pr…

Deformation of a rotated granular pile governed by body-force-dependent friction

T. Irie, R. Yamaguchi, S. Watanabe +1

Although the gravity dependence of granular friction is crucial to understand various natural phenomena, its precise characterization is difficult. We propose a method to character…
