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.

How to form planetesimals from mm-sized chondrules and chondrule aggregates [PDF]
Astronomy & Astrophysics, 2015 The size distribution of asteroids and Kuiper belt objects in the solar system is difficult to reconcile with a bottom-up formation scenario due to the observed scarcity of objects smaller than $\sim$100 km in size.

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.

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 ...

Trace element geochemistry of ordinary chondrite chondrules: The type I/type II chondrule dichotomy [PDF]
, 2015 We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for carbonaceous chondrites, with rare earth element (REE) concentrations ...

Photophoretic Strength on Chondrules. 2. Experiment [PDF]
The Astrophysical Journal, 2014 Photophoretic motion can transport illuminated particles in protoplanetary disks. In a previous paper we focused on the modeling of steady state photophoretic forces based on the compositions derived from tomography and heat transfer.

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.

THE Formation of chondrule-like particles in RF discharge plasma
Physical Sciences and Technology, 2023 Chondrules are fundamental components of chondritic meteorites and play a vital role in understanding the formation of the early solar system. This study focuses on the synthesis of chondrule-like particles in a plasma environment using a radiofrequency
