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...

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...

Low Frequency Eigenmodes of the Earth's Fluid Core
Santiago Andres Triana + Felix Gerick + Jeremy Rekier ...
Earth's rotation period varies over many time scales ranging from diurnal to several milennia, in addition to its secular increase due to tidal friction. These variations...

Assessing the effects of mantle structure on seismic models of the inner core
Daniel Andrew Frost + Barbara A Romanowicz + Prajna Paramita Das
Models of the structure of the inner core are derived from observed seismic data, and this inner core signal may be contaminated by many sources of noise. To study inner core...

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...
