Black hole initial data in Gauss-Bonnet gravity: Momentarily static case

Yoshino, Hirotaka

Understand

We study the method for generating the initial data of black hole systems in Gauss-Bonnet (GB) gravity.

  • The initial data are assumed to be momentarily static and conformally flat.
  • Although the equation for the conformal factor is highly nonlinear, it is successfully solved by numerical relaxation for one-black-hole and two-black-hole systems.
  • The common apparent horizon is studied in the two-black-hole initial data, and the result suggests that the Penrose inequalities are satisfied in this system.
