Vanadium oxide and a sharp onset of cold-trapping on a giant exoplanet [PDF]
Nature, 2023 The abundance of refractory elements in giant planets can provide key insights into their formation histories^ 1 . Owing to the low temperatures of the Solar System giants, refractory elements condense below the cloud deck, limiting sensing capabilities ...

True Polar Wander of Lava Worlds
The Astrophysical Journal Letters, 2023 As one of the most detectable types of terrestrial planets, lava worlds are highly prioritized targets for exoplanet atmosphere characterization since their atmospheres may reveal what they are made of and how.

Evolution of exoplanets and their parent stars [PDF]
EAS Publications Series, 2014 Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on giant gaseous exoplanets orbiting close to solar-type stars.

ExoMDN: Rapid characterization of exoplanet interior structures with Mixture Density Networks [PDF]
Astronomy & Astrophysics, 2023 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 ...

Exoplanet interior retrievals: core masses and metallicities from atmospheric abundances [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The mass and distribution of metals in the interiors of exoplanets are essential for constraining their formation and evolution processes. Never the less, with only masses and radii measured, the determination of exoplanet interior structures is ...

Warm giant exoplanet characterisation: current state, challenges and outlook [PDF]
Frontiers in Astronomy and Space Sciences, 2023 The characterisation of giant exoplanets is crucial to constrain giant planet formation and evolution theory and for putting the solar-system’s giant planets in perspective. Typically, mass-radius (M-R) measurements of moderately irradiated warm Jupiters

Thermal and Orbital Evolution of Low-mass Exoplanets [PDF]
The Astrophysical Journal, 2020 Abstract The thermal, orbital, and rotational dynamics of tidally loaded exoplanets are interconnected by intricate feedback. The rheological structure of the planet determines its susceptibility to tidal deformation and, as a consequence, participates in shaping its orbit.
