Long-lived thermal dynamo generation on differentiated, impact-disrupted planetesimals

Hannah R. Sanderson, James F. J. Bryson, Claire I. O. Nichols

Meteorites containing both metal and silicates indicate that some planetesimals were partially differentiated and/or processes mixed planetesimal cores and mantles post-differentia…

Dynamo generation reveals redox conditions during formation of differentiated planetesimals

Hannah R. Sanderson, James F. J. Bryson, Claire I. O. Nichols

In the early Solar System, an isotopic dichotomy existed between non-carbonaceous (NC) and carbonaceous (CC) planetesimals. Depending on the formation location of these planetesima…

A Collective Trigger for Widespread Planetesimal Formation Revealed by Accretion Ages

James Bryson, Hannah Sanderson, Francis Nimmo +4

The formation of planetesimals was an integral part of the cascading series of processes that built the terrestrial planets. To illuminate planetesimal formation, here we develop a…

Early and elongated epochs of planetesimal dynamo generation

Hannah R. Sanderson, James F. J. Bryson, Claire I. O. Nichols

Accreting in the first few million years (Ma) of the Solar System, planetesimals record conditions in the protoplanetary disc and are the remnants of planetary formation processes.…

Unlocking planetesimal magnetic field histories: a refined, versatile model for thermal evolution and dynamo generation

Hannah R. Sanderson, James F. J. Bryson, Claire I. O. Nichols +1

The thermal and magnetic histories of planetesimals provide unique insights into the formation and evolution of Earth's building blocks. These histories can be gleaned from meteori…
