Accretion onto Some Well-Known Regular Black Holes

Understand

In this work, we discuss the accretion onto static spherical symmetric regular black holes for specific choices of equation of state parameter.

• The underlying regular black holes are charged regular black hole using Fermi-Dirac Distribution, logistic distribution, nonlinear electrodynamics, respectively and Kehagias-Sftesos asymptotically flat regular black hole.
• We obtain the critical radius, critical speed and squared sound speed during the accretion process near the regular black holes.
• We also study the behavior of radial velocity, energy density and rate of change of mass for each regular black holes.
