Lyman Edge Features from Accretion Disks Around Maximally Rotating Supermassive Black Holes
نویسنده
چکیده
We calculate the amplitude of the Lyman discontinuity for an accretion disk around a maximally rotating black hole. The locally emitted disk spectrum is computed with a previously developed numerical model (Sincell & Krolik 1998) and then a new general relativistic ray-tracing code is used to determine the observed spectra as a function of inclination angle, θo. We find that Lyman discontinuities are undetectable for disks viewed at inclinations cos θo <∼ 0.8, but a significant feature remains for disks seen face-on.

Calculation of the relativistic bulk tensor and shear tensor of relativistic accretion flows in the Kerr metric.
In this paper, we calculate the relativistic bulk tensor and shear tensor of the relativistic accretion ows in the Kerr metric, overall and without any approximation. We obtain the relations of all components of the relativistic bulk and shear tensor in terms of components of four-velocity and its derivatives, Christoffel symbols and metric components in the BLF. Then, these components are deri...
متن کاملThe Vertical Structure and Ultraviolet Spectrum of Accretion Disks Heated by Internal Dissipation in Active Galactic Nuclei
We present an improved calculation of the vertical structure and ultraviolet spectrum of a dissipative accretion disk in an AGN. We calculate model spectra in which the viscous stress is proportional to the total pressure, the gas pressure only and the geometric mean of the radiation and gas pressures (cf. Laor & Netzer 1989: LN89). As a result of a more complete treatment of absorptive opacity...
متن کاملDescription of Pseudo-newtonian Potential for the Relativistic Accretion Disk around Kerr Black Holes
We present a pseudo-Newtonian potential for accretion disk modeling around the rotating black holes. This potential can describe the general relativistic effects on accretion disk. As the inclusion of rotation in a proper way is very important at an inner edge of disk the potential is derived from the Kerr metric. This potential can reproduce all the essential properties of general relativity w...
متن کاملHorizon-Penetrating Transonic Accretion Disks around Rotating Black Holes
The stationary hydrodynamic equations for the transonic accretion disks and flows around rotating black holes are presented by using the Kerr-Schild coordinate where there is no coordinate singularity at the event horizon. We use two types of the causal viscosity prescription, and the boundary conditions for the transonic accretion flows are given at the sonic point. For one type of the causal ...
متن کاملBlack Hole Spin Evolution
We consider a subset of the physical processes that determine the spin j ≡ a/M of astrophysical black holes. These include: (1) Initial conditions. Recent models suggest that the collapse of supermassive stars are likely to produce black holes with j ∼ 0.7. (2) Major mergers. The outcome of a nearly equal mass black hole-black hole merger is not yet known, but we review the current best guesses...
