The Planetary Science Journal, 2023 Abstract Outgassing is a central process during the formation and evolution of terrestrial planets and their atmospheres both within and beyond the solar system. Although terrestrial planets’ early atmospheres likely form via outgassing during planetary accretion, the connection between a planet’s bulk composition and its

Modelling compositional convection for applications to exoplanet atmospheres
, 2023 Characterizing the climates of exoplanets— planets orbiting other stars —advances our knowledge of atmospheric science, planetary formation, internal structures and will eventually lead to the holy grail of exoplanet science, detecting biosignatures of alien life. This study focuses on atmospheric convection in super-Earth and sub-Neptune exoplanets, a

The Astrophysical Journal Letters, 2023 Studies of exoplanetary atmospheres have found no definite correlations between observed high-altitude aerosols and other system parameters. This could be, in part, because of the lack of homogeneous exoplanet samples for which specific parameters can be

Exo-Transmit: An Open-Source Code for Calculating Transmission Spectra for Exoplanet Atmospheres of Varied Composition [PDF]
Publications of the Astronomical Society of the Pacific, 2017 We present Exo-Transmit, a software package to calculate exoplanet transmission spectra for planets of varied composition. The code is designed to generate spectra of planets with a wide range of atmospheric composition, temperature, surface gravity, and size, and is therefore applicable to exoplanets ranging in mass and size from hot Jupiters down to ...

, 2020 The detection of habitable exoplanets is an exciting scientific and technical challenge. Owing to the current and most likely long-lasting impossibility of performing in situ exploration of exoplanets, their study and hypotheses regarding their capability to host life will be based on the restricted low-resolution spatial and spectral information of ...

The Astrophysical Journal Letters, 2023 Recently, the first JWST measurement of thermal emission from a rocky exoplanet was reported. The inferred dayside brightness temperature of TRAPPIST-1 b at 15 μ m is consistent with the planet having no atmosphere and therefore no mechanism by which to ...

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 ...
