Did a Complex Carbon Cycle Operate in the Inner Solar System?
Life, 2020 Solids in the interstellar medium consist of an intimate mixture of silicate and carbonaceous grains. Because 99% of silicates in meteorites were reprocessed at high temperatures in the inner regions of the Solar Nebula, we propose that similar levels of

Estimating the Net Magnetic Moment of Geological Samples From Planar Field Maps Using Multipoles
Geochemistry, Geophysics, Geosystems, 2023 Recent advances in magnetic microscopy have enabled studies of geological samples whose weak and spatially nonuniform magnetizations were previously inaccessible to standard magnetometry techniques.

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

Elastic Properties of Returned Samples From Asteroid (162173) Ryugu
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract The successful sample return from asteroid (162173) Ryugu by Hayabusa2 has contributed to our understanding of the solar system evolution. Over the course of the initial sample analysis, various measurements were conducted, such as mineralogical observation, chemical analysis, and mechanical property measurement.

Volatile element evolution of chondrules through time
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance We present time-anchored elemental abundance data for some of the Solar System’s first solids by tracking Pb−Pb dated chondrule compositions.

Planetesimal Impact Vapor Plumes and Nebular Shocks Form Chondritic Mixtures
The Planetary Science JournalThe origin of chondrules and the chondritic sedimentary rocks that dominate the meteoritic record is a long-standing problem in planetary science. Here, we develop a physical model for the formation of chondritic mixtures as an outcome of vaporizing ...

The Short Circuit Instability in Protoplanetary Disks: Processing high temperature minerals
EPJ Web of Conferences, 2013 We introduce a magneto-hydrodynamic instability which occurs, among other locations, in the inner, hot regions of protoplanetary disks, and which alters the way in which resistive dissipation of magnetic energy into heat proceeds.

Magnetic Fields Recorded by Chondrules Formed in Nebular Shocks [PDF]
, 2018 Recent laboratory efforts have constrained the remanent magnetizations of chondrules and the magnetic field strengths to which the chondrules were exposed as they cooled below their Curie points.
