Failed Flash explain the origin of dim supernova


A powerful supercomputer showed that the type of unusually faded stellar explosion can be recognized, in all probability, to the failed attempt to blow up a white dwarf.

A team of scientists led by George Jordan, researchers at Flash Center for Computational Science, University of Chicago, compared the unusually dim supernova type 1a supernovae with the normal of the same type. 


The simulation results allowed researchers to determine that unusual flashes are unsuccessful attempt to blow up when a white dwarf turns ordinary flames, but it does not lead to the formation of the shock front.

These findings are based on the results of computer simulation, which has been used for nearly two million CPU hours on a supercomputer Intrepid, the Blue Gene / P, located at Argonne.
