Abstract
We investigate the structure and the tidal deformability of strange stars (SSs) with a mirror-dark-matter (MDM) core for the standard MIT bag model. We find that to explain the observations of PSR J0740+6620, PSR J0030+0451 and GW170817 simultaneously, SSs in GW170817 should have a MDM core although it is unnecessary for PSR J0740+6620 and PSR J0030+0451 to contain a MDM core. Our study leads to the result that for the standard MIT bag model, the observations of compact stars mentioned above confirm the existence of a dark-matter core inside SSs.
