abstract
Stars of ~8-100 solar masses end their lives as core-collapse supernovae (SNe). In the process they emit a powerful burst of neutrinos, produce a variety of elements, and leave behind either a neutron star or a black hole. The wide mass range for SN progenitors results in diverse neutrino signals, explosion energies, and nucleosynthesis products. A major mechanism to produce nuclei heavier than iron is rapid neutron capture, or the r process. This process may be connected to SNe in several ways. A brief review is presented on current understanding of neutrino emission, explosion, and nucleosynthesis of SNe.

Probing neutrino mass ordering with supernova neutrinos at NO$\nu$A including the effect of sterile neutrinos
Simulations indicate NOvA could distinguish normal from inverted neutrino mass ordering at 5 sigma for a supernova at 5 kiloparsecs, while the neutral-current channel could flag sterile neutrinos.
