Phys. Rev. D 70, 044004 (2004) [6 pages]Physical interpretation of gauge invariant perturbations of spherically symmetric space-timesReceived 12 March 2004; published 9 August 2004 By calculating the Newman-Penrose Weyl tensor components of a perturbed spherically symmetric space-time with respect to invariantly defined classes of null tetrads, we give a physical interpretation, in terms of gravitational radiation, of odd parity gauge invariant metric perturbations. We point out how these gauge invariants may be used in setting boundary and/or initial conditions in perturbation theory. © 2004 The American Physical Society URL:
