On characteristic initial data for a star orbiting a black hole
Nigel T. Bishop, Roberto Gomez, Luis Lehner +2
We take further steps in the development of the characteristic approach to enable handling the physical problem of a compact self-gravitating object, such as a neutron star, in clo…
The 3-dimensional Einstein-Klein-Gordon system in characteristic numerical relativity
W. Barreto, A. Da Silva, R. Gomez +3
We incorporate a massless scalar field into a 3-dimensional code for the characteristic evolution of the gravitational field. The extended 3-dimensional code for the Einstein--Klei…
A numerical examination of an evolving black string horizon
D. Garfinkle, L. Lehner, F. Pretorius
We use the numerical solution describing the evolution of a perturbed black string presented in Choptuik et al. (2003) to elucidate the intrinsic behavior of the horizon. It is fou…
The discrete energy method in numerical relativity: Towards long-term stability
Luis Lehner, David Neilsen, Oscar Reula +1
The energy method can be used to identify well-posed initial boundary value problems for quasi-linear, symmetric hyperbolic partial differential equations with maximally dissipativ…
