Abstract We present a JWST MIRI medium-resolution spectrometer spectrum (5–27 μ m) of the Type Ia supernova (SN Ia) SN 2021aefx at +415 days past B -band maximum. The spectrum, which was obtained during iron-dominated nebular phase, has been analyzed in combination with previous observations to provide first time series analysis an Ia. find that temporal evolution [Co iii ] 11.888 m feature directly traces decay 56 Co. spectra, line profiles, and their are off-center delayed-detonation...
We present a JWST MIRI/MRS spectrum (5-27 $\mathrm{\mu}$m) of the Type Ia supernova (SN Ia), SN 2021aefx at $+415$ days past $B$-band maximum. The spectrum, which was obtained during iron-dominated nebular phase, has been analyzed in combination with previous observations 2021aefx, to provide first time series analysis an Ia. find temporal evolution [Co III] 11.888 $\mathrm{\mu}$m feature directly traces decay $^{56}$Co. spectra, line profiles, and their are off-center delayed-detonation...
