Abstract
We consider gravitational radiation in the nonspherical symmetrical ev olution of supernovae. Unlike the gravitational radiation analysis of Imshennik & Popov performed using the formalism of Peters & Mathews, o ur analysis uses the (PN)(5/2) approximation by Damour & Deruelle and Lincoln & Will. We show that the eccentricity is larger than 0.1 at th e time when the Roche lobe is filled by the low-mass component, demons trating that the conclusion of Imshennik and Popov that the final ecce ntricity is less than 0.1 is incorrect. If the supernova lies in the L arge Magellanic Cloud (R = 50 kpc), we estimate the amplitude of gravi tational waves to be h approximate to 8 x 10(-20). The frequency of th e emitted gravitational waves is about 1 kHz.
