After working with my own data to investigate the supernova SN2001L where the processes are in this web as you can see, I come to the conclusion with my own data that my supernova is type Ia and it's mainly composed of oxygen and hydrogen
As you can see, I said that my supernova is type Ia and it's mainly composed of hydrogen and oxigen but in the scheme, this is not possible. After seeing articles like Planck Collaboration et al. (2016) I have the conclusion that my supernova is type Ia but there aren't articles that specify the chemical composition of SN2001L
