Model of a disk-outflow coupled system: disk-outflow symbiosis

TL;DR

This paper presents a coupled disk-outflow model for black hole systems, showing how outflow power depends on black hole spin, mass, and accretion rate, highlighting the symbiotic relationship between accretion disks and jets.

Contribution

It introduces a novel advective disk-outflow coupled dynamics model that links outflow power to black hole spin and accretion parameters.

Findings

Outflow power increases with black hole spin.

The energetics depend on mass, accretion rate, and spin.

The model explains the disk-outflow symbiosis in black hole systems.

Abstract

Several observational evidences and deeper theoretical insights reveal that accretion and outflow/jet are strongly correlated. We model an advective disk-outflow coupled dynamics. We investigate the properties of the disk-outflow surface and how is it dependent on the spin of the black hole. The energetics of such a symbiotic system strongly depend on the mass, accretion rate and spin of the black holes. The model clearly shows that the outflow power extracted from the disk increases strongly with the spin of the black hole.
