Adiabatic Anisotropic Gravitational Collapse in Painlevé-Gullstrand Coordinates: A Geometric Analysis

G. Abellán, N. Bolívar, A. Alexandrova +1

We present a detailed geometric analysis of adiabatic, anisotropic gravitational collapse formulated in a single Painlevé-Gullstrand coordinate system that covers both the interior…
