Table 1 The physical parameters and times: Gauss–Bonnet coupling constant \(\alpha \), the inner boundary location of computational domain \(r_{in}\), time to need to create a fully formed shock cone \(t_{critial}\) (required time for the steady state), and total simulation time \(t_{total}\). M is the mass of the black hole

From: Bondi–Hoyle accretion around the non-rotating black hole in 4D Einstein–Gauss–Bonnet gravity
