# High accuracy simulations of Kerr tails: coordinate dependence and higher multipoles

@article{Tiglio2008HighAS, title={High accuracy simulations of Kerr tails: coordinate dependence and higher multipoles}, author={Manuel Tiglio and Lawrence E. Kidder and Saul A. Teukolsky}, journal={Classical and Quantum Gravity}, year={2008}, volume={25}, pages={105022} }

We investigate the late-time behavior of a scalar field on a fixed Kerr background using a 2 + 1 dimensional pseudo-spectral evolution code. We compare evolutions of pure axisymmetric multipoles in both Kerr–Schild and Boyer–Lindquist coordinates. We find that the late-time power-law decay rate depends upon the slicing of the background, confirming previous theoretical predictions for those decay rates. The accuracy of the numerical evolutions is sufficient to decide unambiguously between…
