Distinguishing Oceans of Water from Magma on Mini-Neptune K2-18b
The Astrophysical Journal LettersMildly irradiated mini-Neptunes have densities potentially consistent with them hosting substantial liquid-water oceans (“Hycean” planets). The presence of CO _2 and simultaneous absence of ammonia (NH _3 ) in their atmospheres has been proposed as a ...

The Astrophysical JournalPlanet formation models suggest that the small exoplanets that migrate from beyond the snowline of the protoplanetary disk likely contain water-ice-rich cores (∼50% by mass), also known as water worlds.

Interpolation and Synthesis of Sparse Samples in Exoplanet Atmospheric Modeling [PDF]
This paper highlights methods from geostatistics that are relevant to the interpretation, intercomparison, and synthesis of atmospheric model data, with a specific application to exoplanet atmospheric modeling.

Atmospheric characterization of K2-18b [PDF]
openThis thesis investigates the atmosphere of K2-18b, a sub-Neptune exoplanet located in the habitable zone of an M-dwarf star. The study aims to characterize the chemical composition and the temperature-pressure (T-P) profile of the atmosphere to ...

The Astrophysical JournalObservational efforts in the last decade suggest the prevalence of photochemical hazes in exoplanetary atmospheres. Recent JWST observations raise growing evidence that exoplanetary hazes tend to have reflective compositions, unlike the conventionally ...

3D Modeling of Moist Convective Inhibition in Idealized Sub-Neptune Atmospheres
The Astrophysical JournalAtmospheric convection behaves differently in hydrogen-rich atmospheres compared to higher mean molecular weight atmospheres due to compositional gradients of tracers.

A Window for Water-hydrogen Demixing on Warm Metal-rich Sub-Neptunes
The Astrophysical JournalSub-Neptunes represent the largest exoplanet demographic, yet their bulk compositions remain poorly understood. Recent studies suggested that only very cold planets, such as Uranus and Neptune, could experience stratification of volatiles in their ...

FlopPITy: Enabling self-consistent exoplanet atmospheric retrievals with machine learning
Interpreting the observations of exoplanet atmospheres to constrain physical and chemical properties is typically done using Bayesian retrieval techniques.
