Coupled atmospHere Interior modeL Intercomparison (CHILI). I. Evolutionary Modelling -- Primordial Magma Oceans of Earth and Venus

Harrison Nicholls, Joshua Krissansen-Totton, Tim Lichtenberg +22

Earth and Venus represent two evolutionary outcomes arising from initially molten 'magma ocean' periods, followed by lifetimes of chemical and geophysical divergence. Their physics…

Strong and variable stratospheric CO emission from lava-planet 55 Cnc e observed with NIRCam/JWST

Ignas Snellen, Yamila Miguel, Leoni Janssen +4

Some rocky planets orbit so close to their host stars that stellar heating melts their surfaces. They offer a rare glimpse of planets in a magma-ocean state, providing an observabl…

Sensitivity of Dry Lava Planet Atmospheric Emission Spectra to Changes in Lava Compositions

Christiaan P. A. van Buchem, Rojita Buddhacharya, Mantas Zilinskas +3

The atmospheres of hot rocky exoplanets are among the first primary targets of the JWST. Interpreting their atmospheric spectra requires understanding the link between silicate lav…

Reassessing planetary composition: Evidence of rock-dominated envelopes in Uranus and Neptune

Vanesa Ramirez, Yamila Miguel, Saburo Howard

Although Uranus and Neptune are commonly classified as ice giants, their exact compositions remain poorly constrained. Recent studies of outer Solar System bodies challenge the tra…

Mean opacity tables for probing the interior and atmosphere of giant planets

Louis Siebenaler, Yamila Miguel

We present new Rosseland and Planck mean opacity tables relevant to the shallow interiors and atmospheres of giant planets. The tables span metallicities from 0.31 to 50 times sola…

Retrieving interior properties of hot Jupiters with Love numbers and atmospheric measurements

Esther van Dijk, Yamila Miguel

Understanding exoplanet interiors is crucial for interpreting atmospheric observations and constraining their evolution and formation. However, due to limited observational constra…
