A JWST Panchromatic Thermal Emission Spectrum of the Warm Neptune Archetype GJ 436b

The Astrophysical Journal Letters
GJ 436b is the archetype warm Neptune exoplanet. The planet’s thermal emission spectrum was previously observed via intensive secondary eclipse campaigns with Spitzer.

Thermal structure, composition, atmospheric dynamics and long-terme evolution of irradiated exoplanets

Structure thermique, composition, dynamique de l’atmosphère et évolution à long-terme des exoplanètes irradiées Plus d’un millier d’exoplanètes ont été découvertes depuis une dizaine d’années. Plus incroyable encore, nous pouvons maintenant caractériser les atmosphères de ces mondes lointains.

Atmospheric Chemistry of Secondary and Hybrid Atmospheres of Super Earths and Sub-Neptunes

The Astrophysical Journal
The atmospheres of small exoplanets likely derive from a combination of geochemical outgassing and primordial gases left over from formation. Secondary atmospheres, such as those of Earth, Mars, and Venus, are sourced by outgassing. Persistent outgassing

A Possible Metal-dominated Atmosphere below the Thick Aerosols of GJ 1214 b Suggested by Its JWST Panchromatic Transmission Spectrum

The Astrophysical Journal Letters
GJ 1214b is the archetype sub-Neptune for which thick aerosols have prevented us from constraining its atmospheric properties for over a decade. In this study, we leverage the panchromatic transmission spectrum of GJ 1214b established by the Hubble Space

The Impact of Cometary “Impacts” on the Chemistry, Climate, and Spectra of Hot Jupiter Atmospheres

The Astrophysical Journal
Impacts from icy and rocky bodies have helped shape the composition of Solar System objects; for example, the Earth–Moon system, or the recent impact of comet Shoemaker–Levy 9 with Jupiter.
