Does 1a supernova release the same amount of neutrino as type2 supernova?

Does 1a type supernova release the same amount of neutrino as 2 type supernova?

This is an interesting question, and probably one that Stan Woolsey and his colleagues could answer.

Well consider the masses, and Type II would have an advantage, but Type Ia magnitudes are perhaps brighter, indicating a higher reaction density. And then one has to look at the reactions from which neutrinos are formed. Perhaps there is an overlap between heavy Type I's and lighter Type II's - and by heavy, I mean at the top of the population of mass distribution.

I briefly went scanning for neutrino fluxes or densities, but couldn't find anything definitive.

No, 1a supernova and type 2 supernova do not release the same amount of neutrinos. A type 1a supernova is caused by the collapse of a white dwarf star, while a type 2 supernova is caused by the collapse of a massive star. The collapse of a white dwarf does not produce as much energy and therefore does not release as many neutrinos as the collapse of a massive star. Additionally, the composition and density of the stellar core also play a role in the amount of neutrinos released. Therefore, the amount of neutrinos released by a type 1a supernova and a type 2 supernova will differ.
