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…

The Two-Zone Temperature Distribution Model: Inferences on the Structure and Composition of Dusty Protoplanetary Disks
William Grimble, Joel Kastner, B. Sargent +1
In order to understand the mineralogy and structure of protoplanetary disks, it is important to analyze them from both an empirical spectrum-based perspective and a radiative trans…

The compact object and innermost ejecta of SN 1987A
J. Larsson, C. Fransson, P. J. Kavanagh +12
The first JWST observations of SN 1987A provided clear evidence that a compact object is ionizing the innermost ejecta. Here we analyze a second epoch of JWST NIRSpec and MIRI/MRS…
