hej hej, this is my first time post:
is there an equation for the maximum magnitude of supernova Ia? I’ve only seen empirical evidence for the –19.8 intensity. I assume such an equation would be based on the mass of white dwarf when it reaches the Chandrasekhar limit around 1.4 M.
whether or not there is such an equation is not my real question. What I really want to know is the maximum magnitude of a supernova Ia if every thing is the same except the total number of atoms where 1/20 of what we think it is. That is, lets pretend that the white dwarf’s atoms are some how 20 times heavier and hence we need a lot less to reach the Chandrasekhar limit.
I know it might seem silly to pretend that the white dwarf is smaller and made up of heavier [but otherwise normal] particles, but please see past this point for now.
I assume that such a magical mini supernova Ia will have a dimmer maximum magnitude I just want to find out how much dimmer.
Thanks in advance
