Light Element Exsolution in Fe‐Si‐C‐(H) System: A Mechanism for Powering Mercury's Early Core Dynamo
Yuanjing Li + Liangliang Zhang + Fabin Pan ...
Mercury is one of the few terrestrial planets in the solar system with a magnetic field, yet the energy source to power its core dynamo remains unclear to date. Si, C, and...

Measurements of Liquid FeS Density Under Martian Core Conditions: Constraint on Core Density Profile
Fumiya Sakai + Kei Hirose + Shunpei Yokoo ...
The observed large density deficit of the Martian core indicates the presence of large amounts of light elements, and sulfur has been believed to be the dominant one. However,...

Viscous and Magnetic Boundary Layers at the Top of the Core in Geodynamo Models
Dominique Jault + Nathanaël Schaeffer + Nicolas Gillet ...
We investigate the boundary layer at the top of the Earth's core, which acts as a filter between the interior of the core and its surface, where models built from geomagnetic...

Sulfur‐Bearing hcp Iron for Earth's Inner Core
Emiko Sugimura-Komabayashi + Samuel Thompson + Tetsuya Komabayashi ...
Earth's iron core is believed to contain light impurities which should have been included during core formation. In order to place constraints on core composition, here we...
