The Upper Bound of Event Horizon Formation Time in Generalized Oppenheimer-Snyder Collapse
Zhi-Chao Li, H. Khodabakhshi, H. Lu
We prove that, in the framework of the Oppenheimer-Snyder collapse, the Schwarzschild exterior maximizes the event horizon formation time among all a…

Gravitational Collapse: Generalizing Oppenheimer-Snyder and a Conjecture on Horizon Formation Time
H. Khodabakhshi, H. Lu, F. Shojai
We generalize the Oppenheimer-Snyder model of gravitational collapse by considering a broader class of static, spherically symmetric exterior spacetimes, with an interior geometry…
