Growth efficiency, Γ, as described in Eq. (19). Left: mass ratio of f_m = 2. Right: mass ratio of f_m = 8. for a range of Stokes numbers, τ_s, mass-ratios, and binary separation, a_b, at orbital distance of r₀ = 2.5 au from the central star (top panels) and r₀ = 39 au (bottom panels). The most opaque lines denote an orbital separation of a_b = 0.0075R_H while the most transparent lines shows an orbital separation of a_b = 0.05R_H, other lines indicate orbital separations going logarithmic in between.
