2.5-dimensional solution of the advective accretion disk: A self-similar approach

TL;DR

This paper develops a self-similar, analytical 2.5-dimensional model of viscous accretion disks with outflows and jets around black holes, explicitly incorporating vertical flux and conservation laws.

Contribution

It introduces a novel self-similar approach to model the coupled disk-outflow system with vertical flux, advancing understanding of accretion and jet formation.

Findings

Flow parameters depend strongly on viscosity and cooling factors.

Provides analytical solutions for accretion-induced outflows and jets.

Highlights the importance of vertical flux in accretion disk models.

Abstract

We provide a 2.5-dimensional solution to a complete set of viscous hydrodynamical equations describing accretion-induced outflow and then plausible jet around black holes/compact objects. We prescribe a self-consistent advective disk-outflow coupling model, which explicitly includes the information of vertical flux. Inter-connecting dynamics of inflow-outflow system essentially upholds the conservation laws. We provide a set of analytical family of solutions through the self-similar approach. The flow parameters of the disk-outflow system depend strongly on viscosity parameter \alpha and cooling factor f.
