Gas accretion rate as a function of the dust disc radius for the reference case. During the formation phase there is a first regime where the disc radius and accretion rate both increase. In the latter half of the formation phase the disc radius continues to increase, while the gas accretion rate remains almost constant. Once the formation phase is over the accretion rate drops while the dust disc radius still continues to increase. At t ≈ 7.5 × 10⁵ yr the disc radius starts to decrease as the outer parts of the disc begin to drift rapidly. After t ≈ 2.5 × 10⁶ yr the disc is drained of dust.
