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

Chondrule-like objects and Ca-Al-rich inclusions in Ryugu may potentially be the oldest Solar System materials
Chondrule-like objects and Ca-Al-rich inclusions (CAIs) are discovered in the retuned
samples from asteroid Ryugu. Here we report results of oxygen isotope, mineralogical, and …
