  Well supernovas are the graves of stars giving birth to stars, so it is a common, perhaps only known process of star birth ( white dwarf gas accretion is another, somewhat star formation like) , discounting the first star formation cycle. Thats about a dead star. If you talk about dying stars, which are less massive than Chandrasekhar limit but more massive than 1.4 solar masses will end up leaving behind neutron stars after supernova, while the rest > 3 solar masses (Chandrasekhar Limit) will give birth to black holes after the supernova. Stars less massive than 1.4 solar masses first become red giants and finally explode (shed their exterior), leaving behind the core called white dwarf, which in a binary system with a massive gas cloud can attract hydrogen, burn intensely for a short while, explode and repeat. So stars between 1.4 - 3 solar masses are capable mothers 😀
