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...

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...

Unveiling the effect of Ni on the formation and structure of Earth's inner core
Yang Sun + Bo Da + Cai-Zhuang Wang ...
Ni is the second most abundant element in the Earth's core. However, its effects on the inner core's structure and formation process are often overlooked due to its similar...

Influence of an FeS layer on the Thermal and Magnetic Evolution of Mercury's Core
Christopher J Davies + Alfred Wilson + Anne Pommier ...
The existence of an immiscible iron sulfide shell around liquid outer core of planet Mercury has been suggested by geophysical, petrological, and geochemical studies, and...
