Reflation: redox-driven atmospheric inflation as tracer of super-Earth geochemistry
Lorenzo Cesario, Tim Lichtenberg, Mara Attia +3
The paper proposes that the redox state of a super‑Earth’s mantle can cause a temporary re‑inflation of its atmosphere by shifting outgassed volatiles from carbon‑rich to hydrogen‑…
A JWST Transit of a Jupiter Analog: II. A Search for Exomoons
David Kipping, Ben Cassese, Quentin Changeat +3
We present a search for exomoons around the Jupiter-like exoplanet Kepler-167e using a NIRSpec JWST transit. Our 60 hour time series clearly reveals the enormous impact of long-ter…
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…
On the synergetic use of Ariel and JWST for exoplanet atmospheric science
Quentin Changeat, Pierre-Olivier Lagage, Giovanna Tinetti +27
This paper explores the potential for strategic synergies between the JWST and the Ariel telescopes, two flagship observatories poised to revolutionise the study of exoplanet atmos…
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…
