Accretion and evaporation of modified Hayward black hole

mass of the black hole during accretion of the fluid flow, taking into consideration Hawking radiation from the black hole, i.e., evaporation of the black hole, is analyzed. 1 Introduction At present we live in a Universe which is expanding and the expansion rate is increasing, i.e., the Universe is accel-

physical explanation for a black hole mass diminishing may be is that accreting particles of a phantom scalar field have a total negative energy [103]. Similar particles possessing negative energies are created through the Hawking radiation processandalsointheenergyextractionprocessfromablack hole by the Penrose mechanism.

using the metric of the black hole surrounded by quintessence and the definition of the effective potential, we analyzed in detail the null geodesics for different energies. We also described the horizons of the Hayward black hole surrounded by quintessence as well as the shadow of the black hole. PACS numbers: 04.20.-q, 04.70.-s, 04.70.Bw, 04.20.Dw

for the regular Hayward black hole surrounded by quintessence is T = mr(r3 −4β2) 2π(r3 +2β2)2 + (3ωq +1)a 4πr(3ωq +2). (10) Considering only the quantum effects (β 6= 0 and a = 0), this expression of the Unruh-Verlinde temperature is reduced to T = (). = +. =,
