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…
