Scientific paper

Numerical simulation on the supernova explosion of the presupernova model Ws15 M&sun; has been performed using the program WLYW89. It is shown that the supernova prompt explosion may be success by properly adjusting the pressure gradient at the stage of the collapse and the rebound respectively, simultaneously, and not increasing the pressure in the iron core. In the case of insufficient releasing energy by gravity, the adjustment of the pressure gradient has strengthened the mechanism of the transferring energy by convection. This may shorten the time and increase the explosion energy of the supernova explosion. It makes the supernova prompt explosion reality.
