WebThe proton-proton nuclear fusion cycle in a star containing only hydrogen begins with the reaction H + H → D + β + + ν; Q = 1.44 MeV, where the Q -value assumes annihilation of the positron by an electron. The deuterium could react with other deuterium nuclei, but, because there is so much hydrogen, the D/H ratio is held to very low values ... Should the mass of the dying star's core be greater than three to five times the mass of the Sun, then the core will not be able to support its own immense gravity and will collapse into a black hole. This process will also create shock waves that drive material into the surrounding medium, creating the same kind of … See more To understand a supernova, it's important to know a few things about stars.

Revival of a stalled supernova shock by neutrino heating

WebActually, if I remember correctly, a star big enough to end in a supernova, would hardly live a billion years. For a supernova (of type II) a star has to have an intial mass at least 8 times larger than the mass of the sun. The higher mass leads to more pressure on the core and thus an overproportinal speed in the "burning" of hydrogen.
