Accretion rate as function of the initial core mass μ₀. Theoretical curves for the branches corresponding to drift and Hill accretion are plotted as respectively dashed and full lines in grey. The grey full circle marks the transition mass. Black crosses represent the simulated results in a stratified shearing sheet, with Δ = 0.05. Triangles correspond to simulations with modified Δ, a grey upwards pointing triangle corresponds to Δ = 0.07 and a downwards pointing triangle corresponds to Δ = 0.03. In the Hill branch, the position of both triangles lie on top of the black crosses and are omitted for clarity. The grey square shows the result of simulation 1e-3_0.1_b, which includes the particle backreaction.
