In comparing the two alternative explosion mechanisms of core-collapse supernovae (CCSNe). I examine recent three-dimensional (3D) hydrodynamical simulations of CCSNe in the frame of the delayed neutrino explosion mechanism (neutrino mechanism) and argue that these valuable simulations show that neutrino heating can supply a non-negligible fraction of the explosion energy but not the ... https://countryscenesaddleryandpetsuppliers.shop/product-category/gift-cards/
