Surface gravity in spherically symmetric collapsing stars

Abstract Here we consider the generalized Oppenheimer–Snyder collapse of a star into a four-dimensional Einstein-Gauss–Bonnet black hole as well as a class of regular black holes labeled by the polytropic index of the stellar matter. We then analyze the nature of the horizon and the corresponding su...
