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…
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…
Migration of D-type asteroids from the outer Solar System inferred from carbonate in meteorites
Wataru Fujiya, Peter Hoppe, Takayuki Ushikubo +6
Recent dynamical models of Solar System evolution and isotope studies of rock-forming elements in meteorites have suggested that volatile-rich asteroids formed in the outer Solar S…
Origin of Anomalous Xe-H in Nanodiamond Stardust
K. -L. Kratz, K. Farouqi, O. Hallmann +2
Still today, the nucleosynthesis origin of Xe-H in presolar nanodiamonds is far from understood. Historically, possible explanations were proposed by a secondary "neutron-burst" pr…
Origin of anomalous Xe-H in presolar diamonds: Indications of a "cold" r-process
Karl-Ludwig Kratz, Khalil Farouqi, Ulrich Ott
We report on a concerted effort aimed at understanding the nucleosynthesis origin of Xe-H in presolar nanodiamonds. Previously explored possible explanations have included a second…
He and Ne ages of large presolar silicon carbide grains: Solving the recoil problem
U. Ott, P. R. Heck, F. Gyngard +4
Knowledge about the age of presolar grains provides important insights into Galactic chemical evolution and the dynamics of grain formation and destruction processes in the Galaxy.…
