Abstract
This letter argues that gravitational waves, generated in core-collapse of a
pre-supernova star, can produce electromagnetic radiation as the wave
propagates outside the collapsing core. While the energy of this co-produced
electromagnetic radiation is orders of magnitude smaller than the gravitational
radiation, the electromagnetic power is shown to be sufficient to re-ignite
fusion outside of the iron core. The re-ignition of fusion in the silicon layer
of the collapsing star could provide the means to prevent the supernova from
stalling. We conclude that this production of electromagnetic radiation via the
gravitational wave should be included in computer simulations which model
core-collapse supernova.
