Spherical Accretion onto Konoplya Zhidenko Black Holes: Sonic Point Analysis and Fluid Dynamics
This paper investigates spherical accretion onto static Konoplya-Zhidenko black holes by deriving the fluid motion Hamiltonian and analyzing how spacetime deformation influences critical points and flow trajectories across various fluid equations of state, ultimately comparing these effects with those of other modified black hole geometries.
