Mean change in angular momentum of the pebbles as a function of distance to the planet. The ω/ωcrit values show the total spin, expressed in the spin frequency normalised by the critical spin frequency of the planet, that the pebbles retain at distances smaller than the corresponding line. In total, the pebbles enter the atmosphere with approximately 1.684 ωcrit. 35.5% of this spin is absorbed in the outer atmosphere at a distance larger than 0.3 Bondi radii, 26.7% between 0.1 and 0.3 Bondi radii, 27.7% in the inner atmosphere below 0.1 Bondi radii, and finally 10.2% is deposited onto the planet.
