Normalised growth ratios expressed in (as described in Eq. (21)) 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, shown at the top. The most opaque lines denote an orbital separation of a_b = 0.0075R_Η, while the most transparent lines show an orbital separation of a_b = 0.05R_H; other lines indicate orbital separations going logarithmically in between. Relative growth timescales of both bodies as a fraction of the growth timescale of a single body with mass, M = M₁ + M₂ (as described in Eqs. (25) and (26)), shown at the bottom. Black and red lines denote M₁, while the blue lines denote M₂.
