Fleeting but Not Forgotten: The Imprint of Esca** Hydrogen Atmospheres on Super-Earth Interiors
Small, close-in exoplanets are divided into two subpopulations: super-Earths and sub-
Neptunes. Most super-Earths are thought to have lost their primordially accreted hydrogen …

The Effect of Nitrogen on the Dihedral Angle Between Fe− Ni Melt and Ringwoodite: Implications for the Nitrogen Deficit in the Bulk Silicate Earth
Nitrogen (N) is extremely depleted in the bulk silicate Earth (BSE). However, whether the
silicate magma ocean was as N‐poor as the present‐day BSE is unknown. We performed …

Review of experimental and analytical techniques to determine H, C, N, and S solubility and metal–silicate partitioning during planetary differentiation
During their formation, terrestrial planets underwent a magma ocean phase during which
their metallic cores segregated from their silicate mantles and their early atmospheres …
