Description of accretion induced outflows from ultra-luminous sources to under-luminous AGNs
arXiv:0906.0149 · doi:10.1016/j.newast.2009.05.012
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 αand 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.
