Super-Eddington mechanical power of an accreting black hole in M83.
Mass accretion onto black holes releases energy in the form of radiation and outflows. Although the radiative flux cannot substantially exceed the Eddington limit, at which the outgoing radiation pressure impedes the inflow of matter, it remains unclear whether the kinetic energy flux is bounded by this same limit. Here, we present the detection of a radio-optical structure, powered by outflows...
متن کاملSuper - Eddington Black - Hole Models for SS 433
We examine highly super-Eddington black-hole models for SS 433, based on two-dimensional hydrodynamical calculations coupled with radiation transport. The super-Eddington accretion flow with a small viscosity parameter, α = 10, results in a geometrically and optically thick disk with a large opening angle of ∼ 60 to the equatorial plane and a very rarefied, hot, and optically thin high-velocity...
متن کاملSuper-Eddington accretion disc around a Kerr black hole
We calculate the structure of accretion disc around a rapidly rotating black hole with a super-Eddington accretion rate. The luminosity and height of the disc are reduced by the advection effect. In the case of a large viscosity parameter, α > 0.03, the accretion flow strongly deviates from thermodynamic equilibrium and overheats in the central region. With increasing accretion rate, the flow t...
متن کاملSuper-Eddington black hole accretion: Polish doughnuts and slim disks
The theory of highly super-Eddington black hole accretion, Ṁ ≫ ṀEdd, was developed in the 1980s in Warsaw by Paczyński and his collaborators [1]–[9] in terms of Polish doughnuts , i.e. low viscosity, rotating accretion flows that are optically thick, radiation pressure supported, cooled by advection, and radiatively very inefficient. Polish doughnuts resemble fat tori with two narrow funnels al...
متن کاملBlack–Hole Transients and the Eddington Limit
I show that the Eddington limit implies a critical orbital period Pcrit(BH) ' 2 d beyond which black–hole LMXBs cannot appear as persistent systems. The unusual behaviour of GRO J1655-40 may result from its location close to this critical period.
