Estimated mass of accreted solid materials M_acc normalised with πa_p²∑_sol for various planets. The left panel shows M_acc/πa_p²∑_sol as a function of the planetary eccentricty. The different color corresponds to the different semi-major axis of the planet. The planetary mass is set to Jupiter’s mass. The right panel shows M_acc/πa_p²∑_sol as a function of the planetary mass. Here, the different color corresponds to the different eccentricity of the planet. The semi-major axis is set to 1 au. In both panels, the solid and dashed lines show the cases of sin i_p = 10⁻² and 10⁻¹, respectively. We set τ_ecc to 10³ P_orb,p assuming the planet-planet scattering.
