WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research
A. G. Sreejith, L. Fossati, M. Lendl +81
Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…
Atmospheric Supply of Hydrogen Cyanide Is Not the Rate-limiting Step for Prebiotic Chemistry across Rocky Exoplanets
Gergely Friss, Paul I. Palmer, Marrick Braam +1
Hydrogen cyanide (HCN) is crucial for the RNA World hypothesis, forming biomolecules essential for early life. Life likely emerged around 4 billion years ago during the early Arche…
Hydrocarbon complexity and photochemical shielding of prebiotic feedstock molecules in exoplanet atmospheres
Marrick Braam, Ellery Gopaoco, Shang-Min Tsai +4
The potential of prebiotic chemistry to propagate on an exoplanet fundamentally depends on whether the atmospheric conditions can facilitate the production of prebiotic feedstock m…
Climates of Terrestrial Exoplanets and Biosignatures
Siddharth Bhatnagar, Emeline Bolmont, Nikita J. Boeren +18
Understanding the climates of terrestrial exoplanets and the detectability of biosignatures is an inherently interdisciplinary challenge, requiring the integration of insights from…
Observing spatial and temporal variations in the atmospheric chemistry of rocky exoplanets: prospects for mid-infrared spectroscopy
Marrick Braam, Daniel Angerhausen
Future telescopes such as the Large Interferometer For Exoplanets (LIFE) will enable mid-infrared characterisation of the atmospheres of nearby rocky exoplanets. Whilst 4D spatial…
The Oxygen Valve on Hydrogen Escape Since the Great Oxidation Event
Gregory J. Cooke, Dan R. Marsh, Catherine Walsh +2
The Great Oxidation Event (GOE) was a Myr transition circa 2.4 billion years ago that converted the Earth's anoxic atmosphere to one where molecular oxygen (O) was abunda…
Lightning activity on a tidally locked terrestrial exoplanet in storm-resolving simulations for a range of surface pressures
Denis E. Sergeev, James W. McDermott, Lottie Woods +3
Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules into reactive species and thereby af…
Earth-like exoplanets in spin-orbit resonances: climate dynamics, 3D atmospheric chemistry, and observational signatures
Marrick Braam, Paul I. Palmer, Leen Decin +3
Terrestrial exoplanets around M- and K-type stars are important targets for atmospheric characterisation. Such planets are likely tidally locked with the order of spin-orbit resona…
Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood
Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62
The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
The impact of Ozone on Earth-like exoplanet climate dynamics: the case of Proxima Centauri b
Paolo De Luca, Marrick Braam, Thaddeus D. Komacek +1
The emergence of the James Webb Space Telescope and the development of other advanced observatories (e.g., ELTs, LIFE and HWO) marks a pivotal moment in the quest to characterize t…
Stratospheric dayside-to-nightside circulation drives the 3-D ozone distribution on synchronously rotating rocky exoplanets
Marrick Braam, Paul I. Palmer, Leen Decin +2
Determining the habitability and interpreting future atmospheric observations of exoplanets requires understanding the atmospheric dynamics and chemistry from a 3-D perspective. Pr…
3D modelling of the impact of stellar activity on tidally locked terrestrial exoplanets: atmospheric composition and habitability
Robert J. Ridgway, Maria Zamyatina, Nathan J. Mayne +7
Stellar flares present challenges to the potential habitability of terrestrial planets orbiting M dwarf stars through inducing changes in the atmospheric composition and irradiatin…
Lightning-induced chemistry on tidally-locked Earth-like exoplanets
Marrick Braam, Paul I. Palmer, Leen Decin +5
Determining the habitability and interpreting atmospheric spectra of exoplanets requires understanding their atmospheric physics and chemistry. We use a 3-D Coupled Climate-Chemist…
Evidence for chromium hydride in the atmosphere of Hot Jupiter WASP-31b
Marrick Braam, Floris F. S. van der Tak, Katy L. Chubb +1
Context. The characterisation of exoplanet atmospheres has shown a wide diversity in compositions. Hot Jupiters have the appropriate temperatures to host metallic compounds, which…
