  This paper presents the scenario that gravitational waves, generated in
core-collapse of a pre-supernova star, can produce both electromagnetic
radiation and sound radiation as the gravitational wave propagates outward from
the collapsing core. While the energy of this co-produced electromagnetic
and/or sound radiation is orders of magnitude smaller than the initiating
gravitational radiation, the electromagnetic/sonic power may be sufficient to
re-ignite fusion outside the collapsing core. The non-equilibrium re-ignition
of fusion, in roughly the same time frame as the strongest neutrino emissions,
would change the configuration of the pre-supernova star. Although the
co-produced electromagnetic/sonic radiation is not powerful enough to
contribute directly to the supernova, the associated non-equilibrium
re-ignition of fusion could alter the state outside the core. The aim of this
paper is to argue that the effect of this hypothesized co-produced
electromagnetic/sonic radiation should be included in computational models of
core collapse supernovae.
