Description of accretion induced outflows from ultra-luminous sources to under-luminous AGNs

TL;DR

This paper presents a new disc-outflow coupled model to analyze accretion-induced outflows and jets across a range of black hole systems, explaining their energetics and luminosities.

Contribution

The study introduces a novel coupled model that links accretion and outflow dynamics, accounting for viscosity and cooling effects, to explain diverse luminosities in black hole systems.

Findings

Model reproduces ultra-luminous X-ray binary luminosities.

Explains high luminosities of luminous AGNs and quasars.

Fits low-luminous AGNs with sub-Eddington accretion flows.

Abstract

We study the energetics of the accretion-induced outflow and then plausible jet around black holes/compact objects using a newly developed disc-outflow coupled model. Inter-connecting dynamics of outflow and accretion essentially upholds the conservation laws. The energetics depend strongly on the viscosity parameter \alpha and the cooling factor f which exhibit several interesting features. The bolometric luminosities of ultra-luminous X-ray binaries (e.g. SS433) and family of highly luminous AGNs and quasars can be reproduced by the model under the super-Eddington accretion flows. Under appropriate conditions, low-luminous AGNs (e.g. Sagittarius A^*) also fit reasonably well with the luminosity corresponding to a sub-Eddington accretion flow with f\to 1.
