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

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.
