Improved numerical stability of rotating black hole evolution calculations

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We experiment with modifications of the BSSN form of the Einstein field equations (a reformulation of the ADM equations) and demonstrate how these modifications affect the stability of numerical black hole evolution calculations. We use excision to evolve rapid-rotating Kerr-Schild black holes, and obtain accurate and stable simulations for specific angular momenta J/M of up to about 0.9M.
