Numerical calculations of the thermonuclear explosion of a degenerate carbon stellar core
Abstract
Different initial temperature profiles, which imitate the thermal stage of a core's explosion, were used in numerical studies of the thermonuclear explosion of a star's degenerate carbon core. When the most plausible profile is used, a relatively weak stellar explosion producing about 10 to the 50th ergs of kinetic energy is described; this amount of energy falls below the lower limit produced by a supernova. The explosion has the characteristics of a pulsation instability, and the burning is of the deflagration type, which only in some circumstances proceeds to detonation. For the central density value used in these calculations, the formation of a gravitationally bound residue-type neutron star would not occur whatever the initial temperature profile.
