Critical colapse in higher dimensions |
Abstract _ |
We extend Choptuik’s scaling phenomenon found in general relativistic critical gravitational collapse of a massless scalar field to higher dimensions. We find that in the range 4 ≤ D ≤ 11 the behavior is qualitatively similar to that discovered by Choptuik. In each dimension we obtain numerically the universal numbers associated with the critical collapse: the scaling exponent Gamma and the echoing period Delta. The results and their relation to the black hole–black string system are discussed. |
