Magnetic evidence for a partially differentiated carbonaceous chondrite parent body

L Carporzen, BP Weiss… - Proceedings of the …, 2011 - National Acad Sciences
The textures of chondritic meteorites demonstrate that they are not the products of planetary
melting processes. This has long been interpreted as evidence that chondrite parent bodies …

Were chondrites magnetized by the early solar wind?

R Oran, BP Weiss, O Cohen - Earth and Planetary Science Letters, 2018 - Elsevier
Chondritic meteorites have been traditionally thought to be samples of undifferentiated
bodies that never experienced large-scale melting. This view has been challenged by the …

Paleomagnetic evidence for a partially differentiated ordinary chondrite parent asteroid

JFJ Bryson, BP Weiss, B Getzin… - Journal of …, 2019 - Wiley Online Library
The textures and accretion ages of chondrites have been used to argue that their parent
asteroids never differentiated. Without a core, undifferentiated planetesimals could not have …

Chondrites as samples of differentiated planetesimals

LT Elkins-Tanton, BP Weiss, MT Zuber - Earth and Planetary Science …, 2011 - Elsevier
Chondritic meteorites are unmelted and variably metamorphosed aggregates of the earliest
solids of the solar system. The variety of metamorphic textures in chondrites motivated the …

[HTML][HTML] Long-lived magnetism on chondrite parent bodies

J Shah, HC Bates, AR Muxworthy, DC Hezel… - Earth and Planetary …, 2017 - Elsevier
We present evidence for both early-and late-stage magnetic activity on the CV and L/LL
parent bodies respectively from chondrules in Vigarano and Bjurböle. Using micro-CT scans …

Did the carbonaceous chondrites evolve in the crustal regions of partially differentiated asteroids?

S Sahijpal, G Gupta - Journal of Geophysical Research …, 2011 - Wiley Online Library
Carbonaceous chondrites are considered to be the most primitive meteorites that contain
some of the earliest formed solar system phases, eg, Ca‐Al‐rich inclusions and chondrules …

An early solar system magnetic field recorded in CM chondrites

C Cournede, J Gattacceca, M Gounelle… - Earth and Planetary …, 2015 - Elsevier
We present a paleomagnetic study of seven CM carbonaceous chondrites. CM chondrites
are believed to be some of the most chemically primitive materials available in our solar …

No nebular magnetization in the Allende CV carbonaceous chondrite

RR Fu, EA Lima, BP Weiss - Earth and Planetary Science Letters, 2014 - Elsevier
Magnetic fields in the solar nebula may have played a central role in mass and angular
momentum transport in the protosolar disk and facilitated the accretion of the first …

New constraints on the magnetic history of the CV parent body and the solar nebula from the Kaba meteorite

J Gattacceca, BP Weiss, M Gounelle - Earth and Planetary Science Letters, 2016 - Elsevier
Recent paleomagnetic studies of Allende CV chondrite as well as thermal modeling suggest
the existence of partially differentiated asteroids with outer unmelted and variably …

A nonmagnetic differentiated early planetary body

BP Weiss, H Wang, TG Sharp, J Gattacceca… - Earth and Planetary …, 2017 - Elsevier
Paleomagnetic studies of meteorites have shown that the solar nebula was likely
magnetized and that many early planetary bodies generated dynamo magnetic fields in their …
