I have found a supernova that belongs to the constellation Orion, but I have not found much information because it was discovered on February 14 of this year (2020).
I have been able to find a graph that shows the energy spectrum but it is in angstrom. There is no scientific article that mentions the composition of this supernova.
My conclusions
Electron volt is the unit of electric potential and angstrom is the unit of length so you cannot convert electron volt into angstrom.
Acording to sne.space this supernova is type Ia, which means that do not show emission lines typical of hydrogen during the evolution of its brightness. It shows a deep absorption line for silicon, (6200Å/615nm). When its brightness approaches its maximum. Later, its spectrum becomes dominated by iron and cobalt lines.
