Abstract • We propose a new mechanism for gravity-wave production: the conversion of Goldstone bosons to gravitons in the presence of an external gravitational field. We compute the gravity-wave luminosity for the cases in which the external fields are due to various types of black holes: Schwarzschild, Reissner-Nordström, and Kerr. We also consider the case of the Schwarzschild constant-density star. The Goldstone-boson-induced gravity-wave luminosities are largely independent of the mass of the black hole. For the Goldstone bosons we have considered (the omion, recently proposed by Sikivie) these luminosities are small. However this is not due to effects inherent in the conversion process, rather this smallness comes about due to the incoming Goldstone-boson spectrum.
