Phys. Rev. D 70, 084039 (2004) [6 pages]Late time tails from momentarily stationary, compact initial data in Schwarzschild spacetimesReceived 23 August 2004; published 21 October 2004 An ℓ-pole perturbation in Schwarzschild spacetime generally falls off at late times t as t-2ℓ-3. It has recently been pointed out by Karkowski, Świerczyński, and Malec, that for initial data that is of compact support, and is initially momentarily static, the late-time behavior is different, going as t-2ℓ-4. By considering the Laplace transforms of the fields, we show here why the momentarily stationary case is exceptional. We also explain, using a time-domain description, the special features of the time development in this exceptional case. © 2004 The American Physical Society URL:
