Thermoelastic Properties of B2‐Type FeSi Under Deep Earth Conditions: Implications for the Compositions of the Ultralow‐Velocity Zones and the Inner Core
Liu + Jing
The CsCl‐type (B2) phase of FeSi (B2‐FeSi) has been proposed as a candidate phase in the ultralow‐velocity zones (ULVZs) at the base of the lower mantle...

A Scaling Relation for Core Heating by Giant Impacts and Implications for Dynamo Onset
Zhou + Meier + Reinhardt ...
Accretional heating of Earth's interior during formation is pivotal to its subsequent thermal and chemical evolution. In particular, impact heating of Earth's core is expected,...

On the Inner‐Core Differential‐Rotation (Un)Resolvability From Earthquake Doublets: The Traps of Data Selection
Tkalčić
The phenomenon of differential rotation of the Earth's inner core relative to the mantle is a subject of interest in geodynamo modeling that has been validated by seismological...

Inner core convection driven by melt fraction variations
Amelie Schulze + Kang Wei Lim + David Cebron ...
1D models of inner core compaction show that the profile of melt fraction within the inner core is expected to be unstable: the melt fraction is predicted to be higher in...
