Observational constraints of exoplanet clouds

, 2023
We entered a new era in extrasolar planets characterisation. We are indeed given access to constraints on their meteorology. New facilities have been designed specifically for exoplanet atmospheric characterisation.

Distinguishing Oceans of Water from Magma on Mini-Neptune K2-18b

The Astrophysical Journal Letters
Mildly 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 ...

Where Are the Water Worlds? Identifying Exo-water-worlds Using Models of Planet Formation and Atmospheric Evolution

The Astrophysical Journal
Planet 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.

Precise Constraints on the Energy Budget of WASP-121 b from Its JWST NIRISS/SOSS Phase Curve

The Astronomical Journal
Ultra-hot Jupiters exhibit day-to-night temperature contrasts upwards of 1000 K due to competing effects of strong winds, short radiative timescales, magnetic drag, and H _2 dissociation/recombination. Spectroscopic phase curves provide critical insights

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.

Unraveling the Mystery of the Peculiar and Young Hot Jupiter CoRoT-2 b. II. Phase-resolved Emission Spectroscopy with Very Large Telescope/CRIRES+ and Gemini South/IGRINS

The Astronomical Journal
Hot Jupiters are expected to be tidally locked and synchronously rotating due to their short orbital periods. These conditions create large day–night temperature contrasts and are thought to drive eastward superrotating jets.

Lightning activity on a tidally locked terrestrial exoplanet in storm-resolving simulations for a range of surface pressures

Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules into reactive species and thereby affects the atmospheric composition.

The Impact of the Explicit Representation of Convection on the Climate of a Tidally Locked Planet in Global Stretched-mesh Simulations

The Astrophysical Journal
Convective processes are crucial in shaping exoplanetary atmospheres but are computationally expensive to simulate directly. A novel technique of simulating moist convection on tidally locked exoplanets is to use a global 3D model with a stretched mesh ...
