Zoom-whirl sensitivity. (a) Parameter-space heatmap of q from simulation for chosen experimental values µ = 0.01, M_A = 0.35 kg, r₀ = 0.28 m, and M_B = 5.3 kg. For these parameter choices, all long-lived trajectories qualify as zoomwhirl orbits. (b) Parameter-space histogram of experimental trials with target combinations informed by (a); n describes the number of trials per combination. (c, d) Sensitivity analysis of θ_w . Simulated trajectories on a finite table often terminate at the outer boundary; those on an infinite table must terminate at the central boundary. Larger dissipative effects observed in experiment quickly draw MA away from the outer boundary, creating orbits that exclusively terminate at the central boundary. (Outset) Archetypal simulated trajectories demonstrate the discontinuous nature of the sensitivity plots with qualitatively distinct orbits.
