Chondrules are iconic sub-millimeter spheroids representing the most abundant high-
temperature dust formed during the evolution of the circumsolar disk. Chondrules have been …

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 …

Meteorites, and in particular primitive meteorites (chondrites), are irreplaceable probes of
the solar protoplanetary disk. We review their essential properties and endeavour to place …

Low dust opacity spectral indices (β< 1) measured in the inner envelopes of class 0/I young
stellar objects (age∼ 10 4–5 yr) have been interpreted as the presence of (sub-) millimeter …

Nucleosynthetic isotope anomalies of planetary materials provide insight into their genetic
ties, informing our understanding of early Solar System isotopic architecture and evolution …

During protoplanetary disk formation, dust grains located in the outer disk retain their pristine
icy composition, while solids in the inner stellar-heated disk undergo volatile loss. This …

We report a comprehensive study of the ungrouped type 2 carbonaceous chondrite, Tarda,
which fell in Morocco in 2020. This meteorite exhibits substantial similarities to Tagish Lake …

The recent advent of nontraditional isotopic systems has revealed that meteorites display a
fundamental isotopic dichotomy between noncarbonaceous (NC) and carbonaceous (C) …

Context. The formation and evolution of protoplanetary disks remains elusive. We have
numerous astronomical observations of young stellar objects of different ages with their …

The carbonaceous Bencubbin-like (CB), high-metal (CH), and Renazzo-like (CR) chondrites
are metal-rich chondrites that have been suggested to be genetically linked and are …
