Regarding Type Ia, it says the fusion produces the shockwave. Is that correct? Doesn't the matter colliding in the center produce a shockwave, which then ignites fusion and causes the light emission? --

I'm not an expert on supernovae, but from the last i've heard,
the problem is that we don't know the exact mechanism. We aren't
even sure if it is one white dwarf or the collision of two.And
regarding the mechanism, there are theories of "detonation" and
of "deflagration", that I think have to do with where it starts
and how does it expand. I didn't write the particular bit about
Ia for that reason, probably it would be more accurate that we
don't know, and that there are several possible mechanisms. --
