Initial data for black hole-neutron star binaries: a flexible, high-accuracy spectral method
Francois Foucart, Lawrence E. Kidder, Harald P. Pfeiffer +1
We present a new numerical scheme to solve the initial value problem for black hole-neutron star binaries. This method takes advantage of the flexibility and fast convergence of a…
Reducing orbital eccentricity in binary black hole simulations
Harald P. Pfeiffer, Duncan A. Brown, Lawrence E. Kidder +3
Binary black hole simulations starting from quasi-circular (i.e., zero radial velocity) initial data have orbits with small but non-zero orbital eccentricities. In this paper the q…
Initial data for black hole evolutions
Harald P. Pfeiffer
We discuss the initial value problem of general relativity in its recently unified Lagrangian and Hamiltonian pictures and present a multi-domain pseudo-spectral collocation method…
The initial value problem in numerical relativity
Harald P. Pfeiffer
The conformal method for constructing initial data for Einstein's equations is presented in both the Hamiltonian and Lagrangian picture (extrinsic curvature decomposition and confo…
