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…
Ariel Tier 3 Observations: An Opportunity to Explore both Stellar and Planetary Variability through Broad Wavelength Time-domain Spectroscopy
Alexandra H. Thompson, Quentin Changeat, Theresa Luftinger +1
Ariel's Tier 3 observing strategy offers a unique opportunity to explore planetary and stellar variability in the spectral and time domain. However, without the correct toolkit, te…
Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
Olivia Venot, Yamila Miguel, Robin Baeyens +30
Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…
Reflation: redox-driven atmospheric inflation as tracer of super-Earth geochemistry
Lorenzo Cesario, Tim Lichtenberg, Mara Attia +3
We demonstrate that the redox-sensitivity of mantle outgassing can trigger transient episodes of atmospheric re-inflation in highly irradiated and geochemically-reduced super-Earth…
Coupling magma-ocean and atmospheres in spectral retrievals of sub-Neptunes
Yuichi Ito, Quentin Changeat
Recent high-precision atmospheric observations with JWST is enabling detailed characterization of sub-Neptune atmospheres and motivating efforts to understand and constrain their i…
A test of the Dedalus software for exoplanet atmospheric dynamics
Rick Bonhof, Quentin Changeat, James Y-K. Cho
Studying exoplanet flow and variability requires solving atmospheric dynamics equations accurately. Here we use the shallow-water equations to evaluate and employ Dedalus3, a spect…
Pre-computed aerosol extinction, scattering and asymmetry grids for scalable atmospheric retrievals
Maël M. Voyer, Quentin Changeat
The unprecedented wavelength coverage and sensitivity of the James Webb Space Telescope (JWST) permits to measure the absorption features of a wide range of condensate species from…
