Physical analysis of matter accretion and evaporation of holographic massive gravity black hole

We study the matter accretion process onto Schwarzschild black hole in holographic massive gravity and investigate the impact of massive gravitons R and C on the accretion. Using the dynamical approach, we find out the nature of accretion for well known fluids such as ultra-stiff fluid, ultra-relativistic fluid, radiation fluid and sub-relativistic fluid. We discuss the accretion for polytropic fluid and evaluate the mass rate for the Schwarzschild black hole in holographic massive gravity. We also study the evaporation of Schwarzschild AdS black hole in holographic massive gravity. We analyze that initially black hole losses mass quickly, then evaporation process becomes slower and small black hole requires infinite time to evaporate which mean that black hole becomes remnant and third law of black hole thermodynamics satisfies. We observe that massive gravitons R and C have significant impact on the accretion process and Schwarzschild AdS black hole evaporates more quickly in holographic massive gravity as compare to usual Schwarzschild AdS black hole. & COPY; 2023 Elsevier Inc.
