Title: Elucidating early solar system evolution using the magnetism of carbonaceous chondrites
Author: James Bryson from the University of Oxford, UK

During just the first ~5 Myr following the ignition of the Sun, our solar system transformed from a vast protoplanetary disk of dust and gas into an organised collection of planetary bodies. One of the fundamental features that governed this transition was the magnetic field that threaded the disk itself, which played a key role in the transport of mass and angular momentum through the early solar system. Over the last decade, several key and unique insights into the nature of this field have been gleaned from measurements of the ancient magnetic remanences carried by carbonaceous chondrites - a class of aggregate meteorites that originate from the outer solar system. In this talk, I will present an overview of these measurements and use them to illuminate the behaviour of our protoplanetary disk and the formation and evolution of the earliest planetary bodies.
