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…
Photometric Variability and Rotation of Beta Pictoris b from JWST NIRCam Coronagraphic Imaging
Yifan Zhou, Beth A. Biller, Aarynn L. Carter +28
We report the detection of photometric variability in the directly imaged super-Jupiter Pictoris b. Using JWST NIRCam dual-band coronagraphic imaging, we conducted a 16-hour co…
Latitudinal chemical and cloud variations in the atmosphere of a brown dwarf
Benjamin Charnay, Sam de Regt, Matthieu Ravet +8
Brown dwarfs are massive analogues of extrasolar giant planets. Compared to exoplanets whose observations are generally limited by the presence of their bright host star, brown dwa…
Next-generation Exo-REM atmospheric models: application to VHS 1256 b to emulate patchy clouds
Alice Radcliffe, Benjamin Charnay, Anne-Marie Lagrange +7
Condensate clouds are a defining feature of brown dwarf and exoplanet atmospheres, producing a broad range of colours on the CMD and giving rise to spectral features such as the di…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems. VII. Molecular Mapping Performance with JWST/MIRI MRS: VHS 1256 b as a case study
Mathilde Mâlin, Anthony Boccaletti, Benjamin Charnay +29
VHS 1256 b was the first planetary-mass companion to be observed with the James Webb Space Telescope's Mid-Infrared Instrument (JWST/MIRI) using the Medium-Resolution Spectrometer…
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 dataset…
