Chondrule formation by collisions of planetesimals containing volatiles triggered by Jupiter’s formation [PDF]
Scientific ReportsChondrules are spherical or subspherical particles of crystallized or partially crystallized liquid silicates that constitute large-volume fractions of most chondritic meteorites.

Bubbles to Chondrites-I. Evaporation and condensation experiments, and formation of chondrules [PDF]
Progress in Earth and Planetary Science, 2020 We propose a simple model of chondrule formation that is supported by our new experiments. With a laser-heating and inert-gas-cooling technique, we obtained evaporation and condensation pathways starting with chondritic compositions till ends, and ...

Chondrule-like objects and Ca-Al-rich inclusions in Ryugu may potentially be the oldest Solar System materials [PDF]
Nature Communications, 2023 Chondrule-like objects and CAIs in the Ryugu samples are early generations of chondrules and possibly oldest solids in the Solar System. They were transported from the inner solar nebula to the formation location of the Ryugu original parent body.

Abundant microchondrules in 162173 Ryugu suggest a turbulent origin for primitive asteroids [PDF]
Nature CommunicationsChondrules are a characteristic feature of primitive Solar System materials and are common in all primitive meteorites except the CI-chondrites. They are thought to form owing to melting of solid dust aggregates by energetic processing within the solar ...

Chondrule Survivability in the Solar Nebula [PDF]
The Astrophysical JournalThe lifetime of millimeter-sized dust grains, such as chondrules, in the nominal solar nebula model is limited to ∼10 ^5 yr, due to an inward drift driven by gas drag.

Cooling Rates of Chondrules after Lightning Discharge in Solid-rich Environments
The Astrophysical Journal, 2023 Among the several candidate models for chondrule formation, the lighting model has been recognized to be less likely than the other two major models, shock-wave heating and planetesimal collision.

Hysteresis properties of chondritic meteorites: New results for chondrules from the Allende meteorite [PDF]
Geofísica Internacional, 2002 Hysteresis properties of twenty individual chondrules from a ~50 cc piece of the Allende carbonaceous chondritic meteorite, with diameters between about 0.08 and 0.44 cm are reported. Coercive force Hc varies from about 3 mT to 32.5 mT.
