We study the properties of dark stars using non-linear boson self-interaction models. These stars are compact objects formed from bosonic dark matter. We focus on the properties of dark stars such as the mass and radius relation, tidal deformation, and moment of inertia. In this work, bosonic dark particle mass is set to be 300 MeV and 400 MeV. The bosonic self-interaction potential models are |φ|4, cosh-Gordon and Liouville which have the same behavior at low densities but relative difference at high densities. Coupling constants on the corresponding self-interaction potentials are determined by the result of numerical simulations CCDM which requires ratio total cross-section to dark particle mass in the range of .
