Seismological Structure of the Earth's Lowermost Outer Core (F Layer) Beneath the East‐Central Pacific
Toshiki Ohtaki + Satoshi Kaneshima + Taku Tsuchiya
During the inner core solidification, excess light elements are released into the outer core, which causes outer‐core convection. To understand this process, it is important...

Thermodynamic Properties of Liquid Metal Using First‐Principles Molecular Dynamics: Implications for the Compositional and Thermal State of the Earth's Outer Core
Weiyi Liu + Paul D Asimow
The Earth's outer core consists of Fe‐Ni metallic liquid, with minor quantities of light elements such as Si, S, O, C, and H. Accurate equations of state of candidate...

Oxygen Driving Hydrogen Into the Inner Core: Implications for the Earth's Core Composition
Zhiming Zhang + Wei Wang + Jin Liu ...
Earth's core should contain light elements to account for the density deficit relative to pure iron as inferred from seismic observations. Of particular interest is hydrogen,...

Metal‐Silicate Partitioning of Si, O, and Mg at High Pressures and High Temperatures: Implications to the Compositional Evolution of Core‐Forming Metallic Melts
Chang Pu + Zhicheng Jing + Xiujin Gao ...
High‐pressure and high‐temperature experiments were conducted to investigate the partitioning behaviors of Si, O, and Mg between molten Fe‐alloys and silicate...

Dynamo Models With a Mercury‐Like Magnetic Offset Dipole
Patrick Kolhey + Daniel Heyner + Ferdinand Plaschke ...
Mercury has a global magnetic field that is unique in our solar system. It is dominated by a weak axial dipole and a substantial axial quadrupole contribution. The field has...
