Effects of magnetised winds, MHD turbulence, and renewed infall

Determine how dust rings formed by infall-driven gravitational instability evolve in the presence of magnetised winds, magnetohydrodynamic turbulence, or subsequent episodes of mass infall.

Background

The presented model attributes disc transport and structure formation exclusively to gravitoturbulence and considers one finite, axisymmetric infall episode. It does not include magnetised winds, magnetohydrodynamic turbulence, or later infall events, leaving the robustness of the resulting rings under these additional processes unresolved.

References

How do the rings evolve in the presence of magnetised winds, of MHD turbulence, or if there were other subsequent episodes of mass infall?
