Ryugu's nucleosynthetic heritage from the outskirts of the Solar System
Little is known about the origin of the spectral diversity of asteroids and what it says about
conditions in the protoplanetary disk. Here, we show that samples returned from Cb-type …

Is there a genetic relationship between chondrules and matrix?
Chondritic components such as chondrules and matrix are the key time capsules that can
help us understand the evolution and dynamics of the protoplanetary disk from which the …

Origin of isotopic diversity among carbonaceous chondrites
Carbonaceous chondrites are some of the most primitive meteorites and derive from
planetesimals that formed a few million years after the beginning of the solar system. Here …
