We study compactness of dark stars as the function of rotating period, tidal deformation, and moment of inertia of dark stars using vector meson exchange model. These stars are compact object formed of bosonic dark matter. In this work, bosonic dark particle mass is set to be 300 MeV and 400 MeV. We use total cross-section elastic scattering in low-density limit to constraint the effective interaction mass of vector meson. We obtain that compactness exceeds threshold compactness of dark stars using self-interaction model predicted in paper Maselli et all. We also compare the properties of the corresponding dark stars with the ones of the white dwarf and black holes.
