On the gravitational collapse in 4-dimensional Einstein–Gauss–Bonnet gravity

In this paper, we treat 4-dimensional Einstein-Gauss-Bonnet gravity as general relativity with an effective stress-energy tensor. We will study the modified Oppenheimer-Snyder-Datt model of gravitational collapse a star in black hole. The inside geometry is described by spatially flat Friedmann-Robertson-Walker metric and matter distributed uniformly without any pre-assumption about its equation state. exterior hole smoothly matched to interior requirement thin shell. This gives energy density, pressure, state collapsing matter. At end, time evolution event apparent horizons.
