Detection of CO, CO, and HO in the atmosphere of the warm sub-Saturn HAT-P-12b
N. Crouzet, B. Edwards, T. Konings +29
The chemical composition of warm gas giant exoplanet atmospheres (with Teq < 1000 K) is not well known due to the lack of observational constraints. HAT-P-12 b is a warm, sub-Satur…

T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H2O, CH4 and NH3, which exhibit a wealth of absorption features in the mid-infrared…
First unambiguous detection of ammonia in the atmosphere of a planetary mass companion with JWST/MIRI coronagraphs
Mathilde Mâlin, Anthony Boccaletti, Clément Perrot +28
The newly accessible mid-infrared (MIR) window offered by the James Webb Space Telescope (JWST) for exoplanet imaging is expected to provide valuable information to characterize th…
Combined analysis of the 12.8 and 15 JWST/MIRI eclipse observations of TRAPPIST-1 b
Elsa Ducrot, Pierre-Olivier Lagage, Michiel Min +36
The first JWST/MIRI photometric observations of TRAPPIST-1 b allowed for the detection of the thermal emission of the planet at 15 , suggesting that the planet could be a bare…
Water depletion and 15NH3 in the atmosphere of the coldest brown dwarf observed with JWST/MIRI
H. Kühnle, P. Patapis, P. Mollière +21
With a temperature of K WISE0855 is the coldest brown dwarf observed so far. Using the James Webb Space Telescope (JWST) we obtained observations that allow us to charac…
JWST Observations of Young protoStars (JOYS). HH 211: the textbook case of a protostellar jet and outflow
A. Caratti o Garatti, T. P. Ray, P. J. Kavanagh +22
We use the James Webb Space Telescope (JWST) and its Mid-Infrared Instrument (MIRI) (5-28 um), to study the embedded HH 211 flow. We map a 0.95'x0.22' region, covering the full ext…
Unveiling the HD 95086 system at mid-infrared wavelengths with JWST/MIRI
Mathilde Mâlin, Anthony Boccaletti, Clément Perrot +26
Mid-infrared imaging of exoplanets and disks is now possible with the coronagraphs of the MIRI on the JWST. This wavelength range unveils new features of young directly imaged syst…

Jayatee Kanwar, Inga Kamp, Hyerin Jang +20
With the advent of JWST, we acquire unprecedented insights into the physical and chemical structure of the inner regions of planet-forming disks where terrestrial planet formation…
Abundant hydrocarbons in the disk around a very-low-mass star
A. M. Arabhavi, I. Kamp, Th. Henning +40
Very low-mass stars (those <0.3 solar masses) host orbiting terrestrial planets more frequently than other types of stars, but the compositions of those planets are largely unknown…
MINDS: Mid-infrared atomic and molecular hydrogen lines in the inner disk around a low-mass star
