Bondi accretion is computed in Simpson-Visser and charged Simpson-Visser spacetimes, but the reported critical (sonic) radii are not supported by the paper's own equations.
Inflow velocity, density, and pressure profiles, shown in panels (a), (b), and (c), respectively, begin to diverge near the center

Bondi accretion disk luminosity around neutral and charged Simpson-Visser spacetimes
Bondi accretion is computed in Simpson-Visser and charged Simpson-Visser spacetimes, but the reported critical (sonic) radii are not supported by the paper's own equations.
