There are two well-understood regimes of stellar death, although the transition has remained unresolved for 40 years. Stars up to about 8 solar masses lose their outer layers and leave behind a degenerate core -- a white dwarf. More massive stars (above $\sim$ 10 solar masses) produce an iron core, which collapse to a neutron star or black hole in a core-collapse supernova. Theoretically, stars in between ($\sim$ 8--10 solar masses) are expected to produce an electron-capture supernova when the…
