hypernova
Hipernowa - a hypothetical type of high-energy supernova created when an exceptionally massive star collapses due to fusion reactions. Initially, this name referred to an explosion of energy exceeding the brightness of the ordinary supernova more than a hundred times. Later on, this term marked the start of the explosion of the most massive stars, with masses several dozen times that of the sun. The exact value of the star's mass before the collapse, needed to cause its outburst to be hypernous, is not known, and astrophysicists estimate it to be at least several dozen Sun masses, based on theoretical models of star formation and evolution. The percentage of helium and heavy elements in the star is significant, as is the description of the convective transport of energy in the interior of the star, as well as the rate of loss of mass due to star wind in the final stages of its life. During the hyperdriven explosion, the star's core falls directly to the black hole.
