JWST/MIRI observations of the young TWA 27 system: hydrocarbon disk chemistry, silicate clouds, evidence for a CPD

P. Patapis, M. Morales-Calderón, A. M. Arabhavi +39

The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST) enables the characterisation of young self-luminous gas giants at previously inaccessible wavelengths, r…

MIRI-JWST mid-infrared direct imaging of the debris disk of HD106906

Daniel Rouan, Anthony Boccaletti, Clément Perrot +20

We report MIRI-JWST coronagraphic observations at 11.3 and 15.5 mic of the debris disk around the young star HD 106906. The observations were made to characterize the structure, te…

HCN and C2H2 in the atmosphere of a T8.5+T9 brown dwarf binary

Elisabeth C. Matthews, Paul Mollière, Helena Kühnle +22

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…

MINDS. The DR Tau disk I: combining JWST-MIRI data with high-resolution CO spectra to characterise the hot gas

Milou Temmink, Ewine F. van Dishoeck, Sierra L. Grant +29

The MRS mode of the JWST-MIRI instrument has been shown to be a powerful tool to characterise the molecular gas emission of the inner region of planet-forming disks. Here, we analy…

MINDS. JWST-MIRI Reveals a Dynamic Gas-Rich Inner Disk Inside the Cavity of SY Cha

Kamber R. Schwarz, Thomas Henning, Valentin Christiaens +24

SY Cha is a T Tauri star surrounded by a protoplanetary disk with a large cavity seen in the millimeter continuum but has the spectral energy distribution (SED) of a full disk. Her…

15NH3 in the atmosphere of a cool brown dwarf

David Barrado, Paul Mollière, Polychronis Patapis +40

Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits as the governing physical and chemical processes in them are nearly identic…

Imaging detection of the inner dust belt and the four exoplanets in the HR8799 system with JWST's MIRI coronagraph

Boccaletti A., Mâlin M., Baudoz P. +35

The multi planet system HR8799 is the first target observed with MIRI's coronagraphs as part of the MIRI-EC Guaranteed Time Observations exoplanets programme in Nov. 2022. We obtai…
