The objective of the Psyche Magnetometry Investigation is to test the hypothesis that
asteroid (16) Psyche formed from the core of a differentiated planetesimal. To address this …

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 …

Modern meteorite classification schemes assume that no single planetary body could be
source of both unmelted (chondritic) and melted (achondritic) meteorites. This dichotomy is a …

Meteorites contain a record of their thermal and magnetic history, written in the intergrowths
of iron-rich and nickel-rich phases that formed during slow cooling. Of intense interest from a …

Paleomagnetic measurements of ancient terrestrial and extraterrestrial samples indicate that
numerous planetary bodies generated magnetic fields through core dynamo activity during …

The direction in which a planetary core solidifies has fundamental implications for the
feasibility and nature of dynamo generation. Although Earth's core is outwardly solidifying …

The origin of pallasites—stony-iron meteorites mainly composed of olivine and Fe-Ni metal—
is debated and proposed formation scenarios broadly range from models that explain …

The meteorite paleomagnetic record indicates that differentiated (and potentially, partially
differentiated) planetesimals generated dynamo fields in the first 5–40 Myr after the …

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 …

Several paleomagnetic studies have been conducted on five Main Group pallasites:
Brenham, Marjalahti, Springwater, Imilac, and Esquel. These pallasites have distinct cooling …
