Effect of hydrogen on rheology of hcp-Fe
Yu Nishihara + Goru Takaichi + Noriyoshi Tsujino ...
Among candidates for the light element(s) in the Earth’s core, hydrogen is one of the most important candidates. Although many hypotheses have been proposed for the origin...

Physical Properties of Fe-S and Fe-C-S Alloys Under Planetary Core Conditions
Daniele Antonangeli + Andrew King + Attilio Rivoldini ...
The Fe-FeS binary is largely seen as the archetypal system to model the properties of the core of small to medium-sized telluric bodies. Noteworthy, while at the low pressures...

First Measurements of Vertical Fe Flux in Antarctica: Implications for Meteoric Influxes and Lifetimes of Fe and Na
Xinzhao Chu + Chester S. Gardner
Simultaneous observations of meteoric Fe and Na, temperature, and vertical wind with co-located Fe Boltzmann and Na Doppler lidars, enable the first measurements of vertical...

Eutectic Melting Curve for the Fe-FeH System
Shuhei Mita + Kei Hirose + Suyu Fu
H, C, O, Si, and S are thought to be possible major light elements in the Earth’s core, but its composition is still unknown (Hirose et al., 2021). To constrain the core composition,...

Compositional evolution of Europa’s Fe-FeS alloys from accretion to metal melting
Kevin T Trinh + Carver Jay Bierson + Everett Shock ...
Europa, like Ganymede, might host a metallic core made mostly of iron and sulfur. The composition of the core reflects the maximum temperature(s) reached during Europa’s thermal...
