"According to the University of Chicago’s release:

    Jordan and three colleagues, including his chief collaborator on the project, Hagai Perets, assistant professor of physics at Technion – Israel Institute of Technology, have found that the peculiar type Ia supernovae are probably white dwarf stars that failed to detonate. “They ignite an ordinary flame and they burn, but that isn’t followed by a triggering of a detonation wave that goes through the star,” Jordan said. These findings were based on simulations that consumed approximately two million central processing unit hours on Intrepid, the Blue Gene/P supercomputer at Argonne National Laboratory. Full details of the simulations will appear in the Astrophysical Journal Letters.
