Average values of the most massive planets (⟨M₁⟩) and the number of planets (⟨n_last⟩) in a system are shown as a function of the stellar mass. The length of the error bars is equal to the standard deviation. We plotted the results of Σ₁ = 10 g cm⁻² in blue filled symbols, Σ₁ = 30 g cm⁻² in green filled ones, and Σ₁ = 100 g cm⁻² in red filled ones. The open circles are the results of models Ms5Σ100b8 (left) and Ms5Σ100b6 (right), which are plotted at slightly large M_* to avoid overlapping. Left panel: dashed line is the ejection mass (M_ej) given by Eq". (4). The triangles are the mass of the largest and smallest initial protoplanets. The dotted lines are the fitting lines. In the collision-dominated regime (⟨M₁ ⟩ < M_ej), we derived the fitting lines from the mass of the most massive planets and the final number of planets in all of the simulation results. In the ejection-dominated regime (⟨M₁ ⟩ > M_ej), these lines are constant and equal to those values at ⟨M₁⟩ = M_ej.
