- 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 gravitational waves propagate outward from the collapsing core. While the energy of this co-produced electromagnetic and sound radiation is orders of magnitude smaller than the initiating gravitational radiation, the 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 and subsequently the ejecta and the evolution of the stellar expansion of the supernova remnant. Although the co-produced electromagnetic or sound radiation could not contribute directly to the supernova explosion, the associated non-equilibrium re-ignition of fusion would alter the state outside the core leaving an observable signature in the ejecta of the supernova remnant. The aim of this paper is to argue that including this hypothesized co-produced radiation in computational models of core collapse supernovae would contribute to the evolution of the stellar expansion and consequently should be observable in the supernovae remnant, providing a confirmation of the conversion processes for gravitational radiation to electromagnetic and sound radiation.
