ExoMDN: Rapid characterization of exoplanet interior structures with mixture density networks

Astronomy & Astrophysics, 2023
Aims.Characterizing the interior structure of exoplanets is essential for understanding their diversity, formation, and evolution. As the interior of exoplanets is inaccessible to observations, an inverse problem must be solved, where numerical structure models need to conform to observable parameters such as mass and radius.

The ARCiS framework for Exoplanet Atmospheres: The Cloud Transport Model [PDF]

, 2019
Understanding of clouds is instrumental in interpreting current and future spectroscopic observations of exoplanets. Modelling clouds consistently is complex, since it involves many facets of chemistry, nucleation theory, condensation physics ...

Effects of rotation and magnetic fields on the lithium abundance and asteroseismic properties of exoplanet-host stars

, 2010
Aims: The effects of rotation and magnetic fields on the surface abundances of solar-type stars are studied in order to investigate whether the reported difference in lithium content of exoplanet-host stars can be related to their rotational history ...

Gliese 581g as a scaled-up version of Earth: atmospheric circulation simulations

, 2011
We use three-dimensional simulations to study the atmospheric circulation on the first Earth-sized exoplanet discovered in the habitable zone of an M star.

Infrared Observations During the Secondary Eclipse of HD 209458b: I. 3.6-Micron Occultation Spectroscopy Using the VLT [PDF]

, 2002
We search for an infrared signature of the transiting extrasolar planet HD 209458b during secondary eclipse. Our method, which we call `occultation spectroscopy,' searches for the disappearance and reappearance of weak spectral features due to the ...

Vertical structure of an exoplanet’s atmospheric jet stream

Nature
Ultra-hot Jupiters, an extreme class of planets not found in our solar system, provide a unique window into atmospheric processes. The extreme temperature contrasts between their day- and night-sides pose a fundamental climate puzzle: how is energy distributed?

The Radius Cliff is a Waterfall: Explaining Sub-Neptune Exoplanets with Steam Worlds

The Astrophysical Journal
The demographics of Kepler planets provide a key testbed for models of planet formation and evolution, particularly for explaining the radius valley separating super-Earths and sub-Neptunes.
