Accretion and Evaporation of Modified Hayward Black Hole

Understand

First we have assumed the most general static spherically symmetric black hole metric.

• The accretion of any general kind of fluid flow around the black hole have been investigated.
• The accretion of fluid flow around the modified Hayward black hole have been analyzed and we then calculated the critical point, fluid 4 velocity and velocity of sound during accretion process.
• Also the nature of the dynamical mass of black hole during accretion of fluid flow and taking into consideration of Hawking radiation from black hole i.e., evaporation of black hole have been analyzed.
