Gravitational perturbations of the Schwarzschild spacetime: A practical covariant and gauge-invariant formalism
Karl Martel, Eric Poisson
We present a formalism to study the metric perturbations of the Schwarzschild spacetime. The formalism is gauge invariant, and it is also covariant under two-dimensional coordinate…

Gravitational waveforms from a point particle orbiting a Schwarzschild black hole
Karl Martel
We numerically solve the inhomogeneous Zerilli-Moncrief and Regge-Wheeler equations in the time domain. We obtain the gravitational waveforms produced by a point-particle of mass $…
