Dependence of ring architecture on infall parameters

Determine how the number and radial positions of dust rings produced by infall-driven gravitational instability depend on the mass-infall rate and the radial location at which infalling material is deposited.

Background

The study presents one principal simulation with a specified infall rate and deposition interval near 85–100 au. Although that calculation produces multiple rings, it does not establish how ring multiplicity or radial spacing changes when the strength or deposition radius of late infall is varied.
