Hi all,
I am trying to understand the connection between the specific nucleosynthesis that occurs in each step of the explosion mechanism of type Ia supernova (SN Ia).
Let´s see if I got it right, type Ia SN is the complete disruption of a white dwarf(WD) once it passes through the deflagration and detonation phases. Before those phases, as density and temperature increases in the WD, carbon, oxygen and silicon burns. These would be hydrostatic nuclear reactions, right?. Now, my questions are:
Which are the specific nuclear reactions occurring at the degflagration and detonation phase?
Which are the specific so called explosive nucleosynthesis happening in this type of supernova?
Do all the products of the silicon burning are ¨cooked¨ before the explosion?
Which are the specific elements produced during the deflagration and detonation phases?
And about the light curve, why the Si II line is so intense?
Thank you very much!
