Simulation set B (with migration): time evolution of the planet’s acceleration due to the secondary star (${\ddot{x}}_{\text{secondary}}$) normalized by the acceleration due to the primary star (${\ddot{x}}_{\text{primary}}$), color-coded by planet semimajor axis. The gray line represents the planet’s eccentricity. Each panel corresponds to a specific binary case: a_bin = 75 au (left panel), a_bin = 50 au (middle panel), and a_bin = 20 au (right panel), with the embryo initially placed at 5 au. Note the different x-axis, y-axis and color bar scales for each plot.
