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…
