May 13, 2016 at 5:28 comment added ProfRob @SirCumference Type II supernovae are powered by gravitational potential energy, not fusion. The GPE released when a WD collapses to neutron star size in less than a second is greater than can be generated by oxygen fusion (the oxygen is in any case removed by electron capture). Most of the energy is lost as neutrinos. Why wouldn't it leave a remnant?
May 12, 2016 at 23:35 comment added Sir Cumference You just said the collapse of wouldn't trigger burning in an O/Ne/Mg neutron star, and then said the collapse would cause a type of core-collapse supernova. Could you elaborate? Wouldn't the supernova be caused by oxygen fusion? Why would it leave a remnant behind?
