# IMEX evolution of scalar fields on curved backgrounds

@article{Lau2008IMEXEO, title={IMEX evolution of scalar fields on curved backgrounds}, author={Stephen R. Lau and Harald P. Pfeiffer and Janel Brown and Caltech}, journal={Communications in Computational Physics}, year={2008}, volume={6}, pages={1063-1094} }

Inspiral of binary black holes occurs over a time-scale of many orbits, far longer than the dynamical time-scale of the individual black holes. Explicit evolutions of a binary system therefore require excessively many time-steps to capture interesting dynamics. We present a strategy to overcome the Courant-Friedrichs-Lewy condition in such evolutions, one relying on modern implicit-explicit ODE solvers and multidomain spectral methods for elliptic equations. Our analysis considers the model…
