An axisymmetric gravitational collapse code

Abstract: We present a new numerical code designed to solve the Einstein field equations for axisymmetric spacetimes. The long term goal of this project is to construct a code that will be capable of studying many problems of interest in axisymmetry, including gravitational collapse, critical phenomena, investigations of cosmic censorship, and head-on black hole collisions. Our objective here is to detail the (2+1)+1 formalism we use to arrive at the corresponding system of equations and the numerical methods we use to … Show more

“…Still in the 2-D axisymmetric case, fully constrained schemes have been used by Evans [7] and Shapiro and Teukolsky [8] for non-rotating spacetimes, and by Abrahams, Cook, Shapiro and Teukolsky [9] for rotating ones. We also notice that the recent (2+1)+1 axisymmetric code of Choptuik et al [10] is based on a constrained scheme too.…”

“…This is a very ideal case and there have been many attempts to study the problem with less symmetry, for example, in the spacetimes with axial symmetry [6], in which only one spacelike Killing vector exists. However, analytical studies of these spacetimes seem still far beyond our reach.…”
