Stellar gas accretion rate as a function of disc mass using α_min = 10⁻³. The greylines show the reference case dust mass (solid line) and gas (dashed lines). Decreasing α_min results in the disc becoming more gravitationally unstable. This causes the very large increase in the accretion rate in the second half of the formation phase. The accretion rate then drops rapidly until about 0.5 Myr. After this it decreases more slowly. The dust drift turn-over occurs later with lower α_min and the dust disc drains slower. The final gas accretion rate is similar for α_min = 10⁻³ and α_min = 10⁻², but the disc masses of the α_min = 10⁻³ case are higher.
