Knobs and dials of retrieving JWST transmission spectra. II. Impacts of pipeline-level differences on retrieval posteriors
Simon Schleich, Sudeshna Boro Saikia, Quentin Changeat +3
Since the launch of JWST, observations of exoplanetary atmospheres have seen a revolution in data quality. Given that atmospheric parameter inferences depend heavily on the underly…
Knobs and dials of retrieving JWST transmission spectra. I. The importance of p-T profile complexity
Simon Schleich, Sudeshna Boro Saikia, Quentin Changeat +3
We investigate the impact of using multipoint p-T profiles of varying complexity on the retrieval of synthetically generated hot Jupiter transmission spectra modelled after state-o…
Is the atmosphere of the ultra-hot Jupiter WASP-121b variable?
Quentin Changeat, Jack W. Skinner, James Y-K. Cho +12
We present a comprehensive analysis of the Hubble Space Telescope observations of the atmosphere of WASP-121 b, a ultra-hot Jupiter. After reducing the transit, eclipse, and phase-…
15NH3 in the atmosphere of a cool brown dwarf
David Barrado, Paul Mollière, Polychronis Patapis +40
Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits as the governing physical and chemical processes in them are nearly identic…
SO2, silicate clouds, but no CH4 detected in a warm Neptune
Achrene Dyrek, Michiel Min, Leen Decin +44
WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…
A spectroscopic thermometer: individual vibrational band spectroscopy with the example of OH in the atmosphere of WASP-33b
Sam O. M. Wright, Stevanus K. Nugroho, Matteo Brogi +26
Individual vibrational band spectroscopy presents an opportunity to examine exoplanet atmospheres in detail by distinguishing where the vibrational state populations of molecules d…
