Overview

Analysis reveals fluid dynamics at the sonic point in Schwarzschild MOG Black Holes, highlighting modified gravity's impact.

Key Points

  • The mass accretion rate increases with radial distance and the modified gravity parameter α, suggesting significant effects of modified gravity.
  • Critical flow behaviors are identified depending on fluid types, with ultra-relativistic fluids showing both subsonic and supersonic behavior.
  • Phase space analysis visualizes transitions, demonstrating the impact of the equation of state parameter k on fluid dynamics.
  • Different fluid types exhibit varied dynamics near the sonic point, showing the complexity of spherical accretion.
