Distribution of semi-major axes of planets captured by a BH. Each data point represents the mean value of the semi-major axis of a specific planet (Mercury ☿ to Neptune ♆) if it was captured by a BH. The data were compiled from all pre-evolved states of the SS for a given set of initial conditions (impact parameter, b_BH, encounter velocity, v_BH, and the incidence angle, θ_BH) – i.e. the panels do not show how many planets were captured in total (see Fig. B.1 for reference).
