The evolution of the mid-infrared spectrum of SN 1987A observed with the JWST/MIRI-MRS

P. J. Kavanagh, M. J. Barlow, C. Fransson +19

Supernova (SN) 1987A provides a unique laboratory for investigating many aspects of SN physics and evolution. An observation at Day 12927 (35.4 yr) since the explosion with the Mid…

SNR 1987A : Spitzer data from days 6000 to 8000 revisited

Patrice Bouchet, René Gastaud, Alain Coulais +1

An excess emission has been observed by Spitzer in the [3, 5] micron range of the SNR 1987A spectrum. It is generally argued that this excess could be due to the presence of warm a…

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…

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…

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…

A crude but efficient pipeline for JWST MIRI imager : the case of sn1987A

R. Gastaud, A. Coulais

Most of the space projects or large observatories do have official tools like simulators, end-to-end pipelines developed during years by a large team of contributors. They are like…

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…

JWST MIRI Flight Performance: Imaging

Dan Dicken, Macarena García Marín, Irene Shivaei +37

The Mid-Infrared Instrument (MIRI) aboard the James Webb Space Telescope (JWST) provides the observatory with a huge advance in mid-infrared imaging and spectroscopy covering the w…

Emission lines due to ionizing radiation from a compact object in the remnant of Supernova 1987A

C. Fransson, M. J. Barlow, P. J. Kavanagh +31

The nearby Supernova 1987A was accompanied by a burst of neutrino emission, which indicates that a compact object (a neutron star or black hole) was formed in the explosion. There…

JWST MIRI Imager Observations of Supernova SN 1987A

P. Bouchet, R. Gastaud, A. Coulais +31

There exist very few mid-infrared (IR) observations of supernovae (SNe) in general. Therefore, SN 1987A, the closest visible SN in 400 years, gives us the opportunity to explore th…

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…

SO2, silicate clouds, but no CH4 detected in a warm Neptune

Achrene Dyrek, Michiel Min, Leen Decin +44

WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…

MIRISim: A Simulator for the Mid-Infrared Instrument on JWST

P. D. Klaassen, V. C. Geers, S. M. Beard +18

The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST), has imaging, four coronagraphs and both low and medium resolution spectroscopic modes . Being able to s…
