Formation of Ryugu's parent planetesimal beyond the CO snow line from small pebbles: insights from thermal evolution modeling
Sota Arakawa, Hidenori Genda, Noriyuki Kawasaki +3
Astronomical observations of planet-forming circumstellar disks indicate that planetesimals form from 0.1-mm- to 1-cm-sized dust aggregates, commonly called ``pebbles.'' When such…
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…
Hydrothermal activities on C-complex asteroids induced by radioactivity
Wataru Fujiya, Hisato Higashi, Yuki Hibiya +4
C-complex asteroids, rich in carbonaceous materials, are potential sources of Earth's volatile inventories. They are spectrally dark resembling primitive carbonaceous meteorites, a…
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…
