Dimension in a Radiative Stellar Atmosphere
arXiv:gr-qc/0103077 · doi:10.1023/A:1012232608703
Abstract
Dimensional scales are examined in an extended 3+1 Vaidya atmosphere surrounding a Schwarzschild source. At one scale, the Vaidya null fluid vanishes and the spacetime contains only a single spherical 2-surface. Both of these behaviors can be addressed by including higher dimensions in the spacetime metric.
