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…

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…

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…

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…
