Contemporary formation of early Solar System planetesimals at two distinct radial locations
The formation of planetesimals is expected to occur via particle-gas instabilities that
concentrate dust into self-gravitating clumps,–. Triggering these instabilities requires the …

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 …

Formation of rocky super-earths from a narrow ring of planetesimals
K Batygin, A Morbidelli - Nature Astronomy, 2023 - nature.com
The formation of super-Earths, the most abundant planets in the Galaxy, remains elusive.
These planets have masses that typically exceed that of the Earth by a factor of a few …

[HTML][HTML] Nucleosynthetic zinc isotope anomalies reveal a dual origin of terrestrial volatiles
Determining the provenance of volatile elements in Earth is key for understanding the
processes that led to its formation as a habitable planet. We show that the moderately …
