Scientific paper

The paper examines the collapse of iron stellar cores having envelopes with reserves of thermonuclear fuel. A model involving the neutronization of matter is used to explain the collapse, and it is shown that, depending on the temperature of the matter of the envelope before the start of the hydrodynamic contraction, a compact remnant similar to a neutron star or white dwarf results. In the thermonuclear supernova model, the maximum energy of the cast-off envelope resulting from a thermonuclear explosion is approximately (5-7) x 10 to the 49th erg.
