Exploding Stars Explained?
By Robert Naeye



November 3, 2005 | For years theorists have used computer simulations to try to
understand exactly how massive stars explode as supernovae. But they kept
running into a problem: their simulated supernovae usually fizzled. Explaining
how supernovae blow up so violently has remained one of the great unsolved
problems of astrophysics.


Now a team led by Adam S. Burrows (University of Arizona) may have found the key
missing ingredient: sound. The group, whose paper has been submitted to the
Astrophysical Journal, serendipitously discovered in a recent simulation that
acoustic waves generated deep in a collapsing stellar interior have the oomph to
blow apart massive stars. "This could be a completely new paradigm for
supernovae," says Burrows.

There is a "electric star" theory out there that explains it in terms
of electrical fissioning of a star that has too much current density
at its surface. Of course, in this model, stars aren't so much
nuclear furnaces as huge balls of lightning powered by interstellar
electrcal currents flowing through the rarified interstellar medium.
