does the sudden drop of magnitude in the light curve after about 80 days an indication of a black hole? Or, am I misinterpreting the possibilities? I can find no conformation on the web...Lane
Though . . . calculating the gravitational effects of the collapse would be fascinating. The size of that supernova appeared to be enormous. I missed photographing it by 36 hours. I happened to be photographing M101 from May 16, 2023 through May 18, 2023 before the clouds rolled in for a couple of days. (It's generally been a miserable year for astrophotography and photometry at my location.) To think about the swath of space that supernova impacted is mind-boggling.
never mind, I found the answer - it is caused by the ionization/re-ionization of Hydrogen...Lane
