Thick accretion disks with super-Eddington luminosities

Abramowicz, M. A., Calvani, M., Nobili, L.·1980·The Astrophysical Journal

Abstract

A Newtonian version of the theory of thick accretion disks orbiting black holes is described. In view of the present inadequate knowledge of microscopic viscosity processes, this theory adopts a macroscopic approach. All the uncertainties are absorbed in currently arbitrary functions lambda (xi) and f(xi) which describe the (non-Keplerian) angular momentum along the disk, and the outgoing radiation flux in units of the critical flux. Assuming surface distributions of angular momentum and radiation flux, a model of a thick, non-Keplerian accretion disk can be constructed with no knowledge of the viscosity mechanism. Thick accretion disks can have luminosities 100 times above the Eddington limit. Self-consistency constraints for the theory of thick accretion disks with super-Eddington luminosities are studied.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
