Analytic models for gravitational collapse
Original language description
We present two analytical models of gravitational collapse toward the Schwarzschild black hole, starting from the interior of the revisited Schwarzschild solution recently reported [Phys. Rev. D 109, 104032 (2024)]. Both models satisfy some energy conditions at all times as long as the collapse is slower than some limit. While a singularity of the Schwarzschild black hole at the origin (R mu nu alpha beta R mu nu alpha beta similar to r-6) forms immediately after the start of the collapse in one model, such a singularity never appears at finite time during the collapse (except t -> infinity) in the other model. The scheme used shows great potential for studying in detail the appearance of singularities in general relativity.
