Self-gravitational collapse of polytropic mass-losing gaseous discs: effects of outer boundary condition dictated by parent cloud

TL;DR

This paper investigates how the outer boundary conditions, set by the parent molecular cloud, influence the self-gravitational collapse of polytropic, mass-losing gaseous accretion discs, considering viscous and resistive effects.

Contribution

It introduces a model that incorporates the outer boundary condition dictated by the parent cloud into the study of self-gravitating accretion discs with mass and angular momentum loss.

Findings

Outer boundary conditions significantly affect disc stability and structure.

Mass and angular momentum loss alter the collapse dynamics.

Parent cloud constraints modify the disc's evolution.

Abstract

Given the fact that accretion discs are associated with their parent molecular cloud, we studied its effects as a constraint on the outer boundary of the viscous-resistive polytropic self-gravitating accretion flows subject to the mass and angular momentum loss.
