Homogeneous ellipsoids are used to model the gravitational collapse of a stellar core and the subsequent emission of gravitational radiation. The growth of asymmetry caused by the collapse is computed along with the flux and energy spectrum of the gravitational radiation produced as the ellipsoid evolves toward an axisymmetric state following the collapse. In the very low angular momentum limit it is found that a 1 solar mass core of radius equals 1,000,000 cm and angular velocity equals 1,000/sec should emit gravitational radiation by this mechanism with a total energy of approximately 0.0000001 Mc-squared, at a frequency of 1600 Hz and a bandwidth of only about 1.6 Hz.
