Chondrule Dust Rim Growth: Influence of Restructuring Using Molecular Dynamics Simulations

The Astrophysical Journal
We investigate the influence of disruptive collisions on chondrule rim growth, emphasizing the role of kinetic energy in determining the outcomes of these interactions.

Trace element composition of silicate minerals from Kunashak Meteorite (L6)

Записки Горного института
Major (EPMA) and trace (SIMS) element geochemistry in the silicate minerals (olivine, pyroxene and plagioclase) of Kunashak equilibrated ordinary chondrite (L6) is described. No variations in the major element concentrations of the silicate minerals have

Impact-generated Porosity Gradients Controlled Fluid Flow and Aqueous Alteration on the CM Parent Body

The Planetary Science Journal
We investigated the relationship between microporosity, impact deformation, and aqueous alteration in the CM chondrite Murchison using high-resolution (1.86 μ m/voxel) X-ray computed tomography (XCT) combined with a pressurized xenon gas infiltration ...

Synthesis of Si-Fe Chondrule-like Dust Analogues in RF Discharge Plasmas

Applied Sciences
Chondrules 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.

Late Pebble Accretion of Comet 81P/Wild 2 Nucleus: Evidence from a Plagioclase-bearing Chondrule Fragment, Pyxie

The Astrophysical Journal
Comet 81P/Wild 2 is a ∼4.5 km-sized primordial object that almost has not been modified by internal heating by ^26 Al decay. Its nucleus could have been formed by hierarchical agglomeration or gravitational collapse of pebble swarms concentrated by ...

Forming the Noncarbonaceous Chondrite Parent Bodies in the Presence of the Jupiter Barrier

The Astrophysical Journal
Meteorites 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
