From stars to diverse mantles, melts, crusts, and atmospheres of rocky exoplanets
The advent of radial velocity (RV) and transit photometry method has resulted in the
detection of more than 5000 exoplanets since 1995. Of these detected planets, a significant …

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 …

Hydrogenated atmospheres of lava planets: Atmospheric structure and emission spectra
Ultra-hot rocky super-Earths are thought to be sufficiently irradiated by their host star to melt
their surface and allow for long-lasting magma oceans as a result. A number of processes …

On the Formation of Planets in the Milky Way's Thick Disk
T Hallatt, EJ Lee - The Astrophysical Journal, 2025 - iopscience.iop.org
Exoplanet demographic surveys have revealed that close-in (≲ 1 au) small planets orbiting
stars in the Milky Way's thick disk are∼ 50% less abundant than those orbiting stars in the …

A general machine learning model of aluminosilicate melt viscosity and its application to the surface properties of dry lava planets
Ultra-short-period exoplanets like K2-141 b likely have magma oceans on their dayside,
which play a critical role in redistributing heat within the planet. This could lead to a warm …
