The authors implement and validate nuclear networks coupled to GRRMHD with M1 neutrino transport in Gmunu, showing effects on core-collapse supernova shock revival and composition.
Across about 1,500 core-collapse simulations, neutrino heating rises steeply with progenitor compactness, so high-compactness stars revive their stalled shock and explode, contrary to many 1D explodability recipes.
In axisymmetric simulations of a 60 solar mass progenitor, a black hole forms within about a second of shock revival yet the supernova still explodes; final explosion energy ranges from 0.06 to 0.72 times 10^51 erg, ejecta mass from 21.7 to 23.1 solar masses, and 56Ni yield from 0 to 0.018 solar…
Classic piston and thermal-bomb triggers fail to reproduce the explosion-energy versus nickel-yield correlation of neutrino-driven 1D supernova models, while special-trajectory pistons cure fallback but only by importing neutrino-model results.
