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

How uncertainties on stellar atmospheric parameters impact exoplanet studies? [PDF]
, 2017 Exoplanet properties depend on how well the host star is characterized. For instance, the stellar atmospheric parameters (i.e., effective temperature, surface gravity and overall metallicity) are needed to derive the stellar mass and radius by using ...

, 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 ...

Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT Stellar flares present challenges to the potential habitability of terrestrial planets orbiting M dwarf stars through inducing changes in the atmospheric composition and irradiating the planet’s surface in large amounts of ultraviolet light.

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

Simultaneous characterization of the atmospheres, surfaces, and exomoons of nearby rocky exoplanets
Earth and Planetary Physics, 2018 Atmospheric composition is an important indicator of habitability and life. The presence or absence of a large exomoon around an Earth-size exoplanet could have important consequences for planet climate stability.

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 ...
