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…

A new window in time: a mid-infrared slit spectroscopy mode for precision time-series astronomy with JWST/MIRI

Achrene Dyrek, Taylor J. Bell, Pierre-Olivier Lagage +7

The Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST) provides Low Resolution Spectroscopy (LRS) over 5-12 um at a resolving power of R ~ 100. To date,…

A JWST/MIRI view of k Andromedae b: Refining its mass, age, and physical parameters

N. Godoy, E. Choquet, E. Serabyn +7

Context. kAndb is a substellar companion near the planet-brown dwarf boundary, orbiting a B9IV star at 50-100 au. Estimates of its age and mass vary, fueling a decade-long debate.…

First JWST thermal phase curves of temperate terrestrial exoplanets reveal no thick atmosphere around TRAPPIST-1 b and c

Michaël Gillon, Elsa Ducrot, Taylor J. Bell +30

We report JWST/MIRI 15 m phase curves of TRAPPIST-1 b and c, revealing thermal emission consistent with their irradiation levels, assuming no efficient heat redistribution. We f…

Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits

Charles Beichman, Aniket Sanghi, Dimitri Mawet +27

We report on coronagraphic observations of the nearest solar-type star, Cen A, using the MIRI instrument on the James Webb Space Telescope. With three epochs of observation (Au…
