The investigation of thin accretion disc surrounding the Einstein‐ Euler‐ Heisenberg‐ Anti‐ de Sitter black hole is demonstrated. Additionally, the black hole event horizons and compute their effective potential and equations of motion is analyzed. The specific energy, specific angular momentum, and specific angular velocity of the particles that move in circular orbits above the thin accretion disk are obtained. Also, the effects of parameters of the Einstein‐ Euler‐ Heisenberg‐ Anti De sitter black hole on specific angular velocity, specific heat energy, and specific angular momentum, have been discussed in detail. The positions of the innermost stable circular orbits and illustrate the effective potential are displayed. Furthermore, the circular orbits of black hole are obtained numerically and locates the position of the innermost stable circular orbit and event horizon. Also, the Gamma ray burst emitted from the Einstein Euler Heisenberg Anti de sitter black hole is studied.

“…Let us consider a simple non-relativistic model of an accretion disk around a compact central object. Recent investigation on this issue in different perspective are [44][45][46][47]. Here it is assumed that matter spirals inwards by losing angular momentum which, because of turbulent viscous density be transferred outward through the disk.…”

We study quantum gravity effects on radiation process of the thin accretion disks around Schwarzschild like black-hole. The quantum gravity correction is invoked through the framework of generalization of uncertainty which is equivalent to renormalization group improved quantum gravity and maintain the limit of the asymptotically safe preposition of gravity. It admits a free parameter that encodes the quantum effects on the spacetime geometry. It allows us to study how the thermal properties of the disk are modified in the quantum regime. We explicitly make estimations of quantum correction to the time averaged energy flux, the temperature of the disk, the differential luminosity, and the conversion efficiency of accreting mass into radiation. We observe a conspicuous shifting of the radius of the innermost stable circular orbit (ISCO) toward small values together with an enhancement of the maximum of the values of the average thermal radiation and greater conversion efficiency of accreting mass into radiation compared to the classical gravity scenario.

“…The steady-state thin accretion disk model is the simplest theoretical model in which the disk has negligible thickness [13][14][15]. The physical properties of matter forming a thin accretion disk in a variety of background spacetimes have been discussed extensively, see for example [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. The signatures appeared in the energy flux and the spectrum emitted by the disk can provide us not only the information about BHs, but also the verification of modified gravity theories [30].…”

We consider the accretion process in the thin disk around a black hole in Einstein-aether-scalar theory. We probe the effects of the model parameter on the physical properties of the disk. The results show that with increasing value of the parameter, the energy flux, the radiation temperature, the spectra cut-off frequency, the spectra luminosity, and the conversion efficiency of the disk decrease. The disk is hotter and more luminous than that in general relativity for negative parameter, while they are cooler and less luminous for positive parameter. We also find some values of the parameter allowed by the theory are excluded by the physical properties of the disk.
