CO Self-Shielding as a Mechanism to Make 16O-Enriched Solids in the Solar Nebula
Challenges, 2014 Photochemical self-shielding of CO has been proposed as a mechanism to produce solids observed in the modern, 16O-depleted solar system. This is distinct from the relatively 16O-enriched composition of the solar nebula, as demonstrated by the oxygen ...

Synthesis of Si-Fe Chondrule-like Dust Analogues in RF Discharge Plasmas
Applied SciencesChondrules are tiny particles that occur in stony meteorites and are considered as the building blocks of early asteroids and planets. It is believed that they were formed by the fast heating of the dust in the solar nebula.

Forming the Noncarbonaceous Chondrite Parent Bodies in the Presence of the Jupiter Barrier
The Astrophysical JournalMeteorites can be divided into two groups—noncarbonaceous chondrite like (NC) and carbonaceous chondrite like (CC)—with distinct stable-isotope compositions. Parent bodies of NC and CC meteorites have overlapping formation ages. This suggests they formed
