▪ Abstract Chondrules are∼ 1-mm igneous droplets in primitive meteorites, and their
abundance suggests widespread melting in the protoplanetary disk. Chondrules with relict …

Millimeter‐scale rock particles called chondrules are the principal components of the most
common meteorites, chondrites. Hence, chondrules were arguably the most abundant …

Full equilibrium calculations of the sequence of condensation of the elements from cosmic
gases made by total vaporization of dust-enriched systems were performed in order to …

Astronomical observations have shown that protoplanetary disks are dynamic objects
through which mass is transported and accreted by the central star. This transport causes …

We present a model for the thermal processing of particles in shock waves typical of the
solar nebula. This shock model improves on existing models in that the dissociation and …

Chondrule textures depend on the extent of melting of the chondrule precursor material
when cooling starts. If viable nuclei remain in the melt, crystallization begins immediately …

We review a number of constraints that have been placed on the formation of chondrules
and show how these can be used to test chondrule formation models. Four models in …

The petrologic and geochemical properties of chondrules as well as results of experimental
studies provide strong constraints on chondrule-formation models. Nebular formation is …

Chondrules are submillimeter spheres that constitute up to 80% of the volume of the most
primitive meteorites. That they result from the solidification of a melt in low-gravity in the early …

High-precision oxygen three-isotope measurements of olivine and pyroxene were
performed on 33 chondrules in the Yamato 81020 CO3. 0 chondrite by secondary ion mass …
