Description
We find that the existence of strange stars is ruled out by the dimensionless tidal deformability of a 1.4 M_sun star of GW170817 and the mass of PSR J0740+6620 , both for the standard MIT bag model and for the density dependent quark mass model. However, if non-Newtonian gravity effects are considered, strange stars can exist for certain ranges of the values of the non-Newtonian gravity parameter. An alternative explanation to the observations is to suppose that strange stars in GW170817 have a dark-matter core.
