Initial data for black hole-neutron star binaries: a flexible, high-accuracy spectral method

Foucart, Francois, Kidder, Lawrence E., Pfeiffer, Harald P. et al.

Understand

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 multidomain spectral representation of the initial data to construct high-accuracy solutions at a relatively low computational cost.
  • We provide convergence tests of the method for both isolated neutron stars and irrotational binaries.
  • In the second case, we show that we can resolve the small inconsistencies that are part of the quasi-equilibrium formulation, and that these inconsistencies are significantly smaller than observed in previous works.
