Transmission strings: a technique for spatially mapping exoplanet atmospheres around their terminators [PDF]

Monthly notices of the Royal Astronomical Society, 2022
Exoplanet transmission spectra, which measure the absorption of light passing through a planet’s atmosphere during transit, are most often assessed globally, resulting in a single spectrum per planetary atmosphere.

Investigating the detectability of hydrocarbons in exoplanet atmospheres with JWST [PDF]

Astronomy & Astrophysics, 2022
Aims. We investigate at what abundances various hydrocarbon molecules (e.g. acetylene (C 2 H 2 ), ethylene (C 2 H 4 ), and methane (CH 4 )) become detectable when observing the atmospheres of various planets using the James Webb Space Telescope (JWST ...

The impact of time-dependent stellar activity on exoplanet atmospheres [PDF]

Monthly notices of the Royal Astronomical Society, 2022
M-dwarfs are thought to be hostile environments for exoplanets. Stellar events are very common on such stars. These events might cause the atmospheres of exoplanets to change significantly over time.

Identification of carbon dioxide in an exoplanet atmosphere [PDF]

Nature, 2022
AbstractCarbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2is an indicator of the metal enrichment (that is, elements heavier than helium, also called ‘metallicity’)1–3, and thus the formation processes of the primary atmospheres of hot gas giants4–6. It is also one of

EUV irradiation of exoplanet atmospheres occurs on Gyr time-scales [PDF]

, 2020
Exoplanet atmospheres are known to be vulnerable to mass loss through irradiation by stellar X-ray and extreme-ultraviolet emission. We investigate how this high-energy irradiation varies with time by combining an empirical relation describing stellar X ...

EXOPLINES: Molecular Absorption Cross-section Database for Brown Dwarf and Giant Exoplanet Atmospheres [PDF]

Astrophysical Journal Supplement Series, 2021
Stellar, substellar, and planetary atmosphere models are all highly sensitive to the input opacities. Generational differences between various state-of-the-art stellar/planetary models arise primarily because of incomplete and outdated atomic/molecular ...

Simulating gas giant exoplanet atmospheres with Exo-FMS: Comparing semi-grey, picket fence and correlated-k radiative-transfer schemes. [PDF]

Monthly notices of the Royal Astronomical Society, 2021
Radiative-transfer (RT) is a fundamental part of modelling exoplanet atmospheres with general circulation models (GCMs). An accurate RT scheme is required for estimates of the atmospheric energy transport and for gaining physical insight from model ...
