Self-collimated axial jets seeds from thin accretion disks

TL;DR

This paper proposes that a crystalline magnetic field structure in accretion disks can naturally produce highly collimated axial jets, with plasma ejection consistent with observed accretion rates.

Contribution

It introduces a novel model where crystalline magnetic structures induce jet seeds with natural collimation and plasma ejection in accretion disks.

Findings

High collimation of axial jets predicted by the model.

Jet seed plasma ejection aligns with observed accretion rates.

Crystalline magnetic structures influence disk fragmentation and jet formation.

Abstract

We show how an appropriate stationary crystalline structure of the magnetic field can induce a partial fragmentation of the accretion disk, generating an axial jet seed composed of hot plasma twisted in a funnel-like structure due to the rotation of the system. The most important feature we outline is the high degree of collimation, naturally following from the basic assumptions underlying the crystalline structure. The presence of non-zero dissipative effects allows the plasma ejection throughout the axial jet seed and the predicted values of the accretion rate are in agreement with observations.
