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…
The JWST weather report: Unravelling the atmospheric variability of isolated worlds using principal component analysis
Merle A. Schrader, Johanna M. Vos, Evert Nasedkin +17
The paper uses principal component analysis on JWST/NIRSpec time‑series spectra of the brown dwarf SIMP‑0136 to identify two dominant patterns of variability, linking them to tempe…
Silicate Clouds, SiO, and Molecular Trends across the L-T Sequence: A JWST/MIRI LRS Spectral Library of Brown Dwarfs
Sam Barber, Stanimir Metchev, Genaro Suárez +12
We present the results of a survey program with JWST's MIRI LRS that obtained 514 m R~100 spectra of twenty-three L0T6 dwarfs. This spectral type range spans the formation…
On the Detectability of Volcanic Exo-Ios That May Fuel Auroras on Super-Jupiters
Brooke Kotten, Mary Anne Limbach, Johanna M. Vos +12
The paper evaluates whether JWST transit observations can detect volcanic exomoons around aurorally active super‑Jupiters, demonstrating feasibility for moons with mass ratios simi…
Inspecting Cloudy Substellar Atmospheres with JWST MIRI Synthetic Magnitudes from Spitzer Mid-infrared Spectra
Jolie LHeureux, Genaro Suárez, Johanna M. Vos +4
We examine the positions of substellar objects in mid-infrared color-magnitude and color-color diagrams to distinguish between cloudy and cloud-free atmospheres. Using Spitzer mid-…
Panchromatic View of the Frigid Jovian Exoplanet COCONUTS-2 b
Matthieu Ravet, Mickaël Bonnefoy, Gaël Chauvin +24
We use a high signal-to-noise MIRI-LRS spectrum (5.45 - 11 m, R ) of COCONUTS-2~b revealing prominent molecular features of HO, CH and NH. This datase…
