The effect of gaseous accretion disk on dynamics of the stellar cluster in AGN

TL;DR

This paper investigates how a gaseous accretion disk influences the dynamics and density distribution of a central stellar cluster around a supermassive black hole in active galactic nuclei, highlighting the dissipative effects and asymmetries introduced.

Contribution

It introduces the Stardisk model to analyze the impact of a rotating gaseous accretion disk on the phase space and density of the central star cluster in AGN.

Findings

Changes in density distribution of the star cluster due to the disk

Asymmetry in phase space caused by dissipative forces

Alterations in cluster dynamics linked to the disk's rotation

Abstract

There is a supermassive black hole, a gaseous accretion disk and compact star cluster in the center of active galactic nuclei, as known today. So the activity of AGN can be represented as the result of interaction of these three subsystems. In this work we investigate the dynamical interaction of a central star cluster surrounding a supermassive black hole and a central accretion disk. The dissipative force acting on stars in the disk leads to an asymmetry in the phase space distribution of the central star cluster due to the rotating accretion disk. In our work we present some results of Stardisk model, where we see some changes in density and phase space of central star cluster due to influence of rotating gaseous accretion disk.
