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…

A Mid-Infrared Spectroscopic Study of Young Stellar Objects in the SMC Region NGC 346: JWST Detects Dust, Accretion, Ices and Outflows
Nolan Habel, Omnarayani Nayak, Patrick J. Kavanagh +13
We present mid-infrared spectroscopic observations of intermediate- to high-mass young stellar objects (YSOs) in the low-metallicity star-forming region NGC 346 located within the…

First detection of ices in intermediate-mass young stellar objects beyond the Milky Way
Guido De Marchi, Nolan Habel, Margaret Meixner +15
Using NIRSpec on JWST, we studied a sample of 15 intermediate-mass (1.8-4.1 Msun) young stellar objects (YSOs) previously identified with MIRI photometry in the low-metallicity NGC…
