Abstract

We discuss the emission of gravitational waves from stellar collapse,with particular emphasis on the emission arising from convection above the surface of the proto-neutron star. We analytically estimate an upper limit to the gravitational wave emission from this convection. We also present results from the first 3-dimensional core-collapse simulations including realistic equations of state and neutrino physics and calculate the resultant gravitational wave signal from these collapse simulations. Convective overturns do not produce observable gravitational wave emission nor does this emission remove enough energy to effect the convective motions. But asymmetries in supernova are an almost certainty, and these asymmetries (possibly caused by rotation) will produce strong gravitational wave emission.
