| contents | We systematically investigate the observable properties of dark matter-admixed quark stars (DQSs) using the confined-isospin-density-dependent-mass model in combination with the generic bosonic self-interacting dark matter model. Our results show that the dark matter (DM) can significantly influence the properties of quark stars including the mass, radius, and the central pressure at the maximum mass configurations. Moreover, we observe that the mass of DMparticles and the DMfraction significantly affect the types of stellar configurations, and we study these configurations in detail under various scenarios and predict the possibility that two recently observed peculiar objects HESS J1731-347 and PSR J014-4002E are DQSs. |
