DOI: 10.1088/1475-7516/2022/02/034
Abstract: The accretion disk is formed by particles moving in closed orbits around a compact object, whose physical properties and the electromagnetic radiation characteristics are determined by the space-time geometry around the compact object. In this… read more here.

DOI: 10.1093/mnras/staa1591
Abstract: The analysis of the thermal spectrum of geometrically thin and optically thick accretion disks of black holes, the so-called continuum-fitting method, is one of the leading techniques for measuring black hole spins. Current models normally… read more here.

DOI: 10.1093/mnras/staa3052
Abstract: We derive several analytical relations and approximate solutions for the local vertical structure of viscous thin accretion discs. Under the alpha prescription, when the viscous heating is proportional to the gas pressure p, we derive… read more here.

DOI: 10.1103/physrevd.101.023002
Abstract: We construct the relativistic standard steady, optically thick, cold and geometrically thin accretion disk around a distorted Schwarzschild black hole. The distortion of this static and axially symmetric black hole solution, is connected to an… read more here.

DOI: 10.1103/physrevd.104.104055
Abstract: We study stable circular orbits (SCO) around static spherically symmetric configuration of General Relativity with a non-linear scalar field (SF). The configurations are described by solutions of the Einstein-SF equations with monomial SF potential V… read more here.
