The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future

Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123

JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…

Comparing Grid Model Fitting Methodologies for Low-Temperature Atmospheres: Markov Chain Monte Carlo versus Random Forest Retrieval

Anna Lueber, Adam J. Burgasser

The atmospheres of low-temperature stars, brown dwarfs, and exoplanets are challenging to model due to strong molecular features and complex gas and condensate chemistry. Self-cons…

Near-instantaneous Atmospheric Retrievals and Model Comparison with FASTER

Anna Lueber, Konstantin Karchev, Chloe Fisher +3

In the era of the James Webb Space Telescope (JWST), the dramatic improvement in the spectra of exoplanetary atmospheres demands a corresponding leap forward in our ability to anal…

The Retrieved Atmospheric Properties of the Sub-stellar Object VHS 1256 b from Analyzing HST, VLT and JWST Spectra

Anna Lueber, Kevin Heng, Brendan P. Bowler +3

Motivated by the observed ~30% variations in flux from the L7 dwarf VHS 1256 b, we subjected its time-resolved Hubble Space Telescope (HST) WFC3 spectra (measured in two epochs in…

Information content of JWST spectra of WASP-39b

Anna Lueber, Aline Novais, Chloe Fisher +1

WASP-39b was observed using several different JWST instrument modes and the spectra were published in a series of papers by the ERS team. The current study examines the information…

Retrieval Study of Brown Dwarfs Across the L-T Sequence

Anna Lueber, Daniel Kitzmann, Brendan P. Bowler +2

A large suite of 228 atmospheric retrievals is performed on a curated sample of 19 brown dwarfs spanning the L0 to T8 spectral types using the open-source Helios-r2 retrieval code,…

The Mantis Network I: A standard grid of templates and masks for cross-correlation analyses of ultra-hot Jupiter transmission spectra

Daniel Kitzmann, Jens H. Hoeijmakers, Simon L. Grimm +3

The atmospheres of ultra-hot Jupiters are highly interesting and unique chemical laboratories. Due to the very high atmospheric temperatures, their chemical composition is dominate…
