Comparison of the morphology, density, and average mass of stars for the five models with different M₀ and the minimum Δ referring to the OB-min model in the M800R2 set. For each model, the three panels show the number density map of stars in the spherical coordinate system of the Galactocentric reference frame, the histogram of star counting (N_s), and the average mass of stars (⟨m_s⟩) along the longitude, respectively. The compacted objects (WDs, NSs, and BHs) are excluded.
