Wormholes and trumpets: the Schwarzschild spacetime for the moving-puncture generation

Hannam, Mark, Husa, Sascha, Ohme, Frank et al.

Understand

We expand upon our previous analysis of numerical moving-puncture simulations of the Schwarzschild spacetime.

  • We present a derivation of the family of analytic stationary 1+log foliations of the Schwarzschild solution, and outline a transformation to isotropic-like coordinates.
  • We discuss in detail the numerical evolution of standard Schwarzschild puncture data, and the new time-independent 1+log data.
  • Finally, we demonstrate that the moving-puncture method can locate the appropriate stationary geometry in a robust manner when a numerical code alternates between two forms of 1+log slicing during a simulation.
