Experimental evidence for granular shear-flow instability in the Epstein regime
Holly L. Capelo, Jean-David Bodénan, Martin Jutzi +7
Stability analysis of two-fluid protoplanetary disc models has enriched our understanding of how solids can grow into larger bodies called planetesimals. Dust particles entrained i…
Stellar Interpretation of Meteoritic Data and PLotting for Everyone (SIMPLE): Isotope Mixing Lines for Six Sets of Core-Collapse Supernova Models
Marco Pignatari, Mattias Ek, Georgy V. Makhatadze +15
Bulk meteorites and their inclusions exhibit, for many chemical elements, isotopic variability produced by nucleosynthetic events in stars and supernovae before the formation of th…
Interstellar Ices as Carriers of Supernova Material to the Early Solar System
Martin Bizzarro, Martin Schiller, Jesper Holst +10
Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiti…
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…
Presolar Grains As Probes of Supernova Nucleosynthesis
Nan Liu, Maria Lugaro, Jan Leitner +2
We provide an overview of the isotopic signatures of presolar supernova grains, specifically focusing on 44Ti-containing grains with robustly inferred supernova origins and their i…
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…
