Including the backreaction friction force on the gas, a core of μ = 10^-3 accretes particles of τ_f = 0.1 (third and last panels), even in presence of turbulence caused by the streaming instability. The turbulence has first been given 20 orbits (~126 Ω^-1) to saturate (first and second panels), before the core is inserted. From the full Hill sphere, r_H/H ≈ 0.07, pebbles are attracted in a prograde motion to the core (third panel). As before, the colour bar in the first panel gives the particle surface density. The insets show the azimuthally averaged particle density and vertical extent of the particle layer. For clarity, in the insets the colour coding covers a twice as wide range in particle overdensity, compared to the surface density plots.
