Classification of Oppenheimer-Snyder Collapse: Singular, Bouncing, and Soft-Landing Scenarios
Zhi-Chao Li, H. Khodabakhshi, H. Lu
We study Oppenheimer-Snyder (OS) gravitational collapse matched to a general static, spherically symmetric exterior spacetime. Unlike the Schwarzschild case, two new features can a…

Black p-brane Thermodynamics without Constructing Solutions
Bing-Yang Han, H. Lu
This paper generalizes the method used in the previous article 2512.09930 to black -brane thermodynamics in arbitrary dimensions containing black holes and strings as special ca…

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…
