Constraints from compact star observations on non-Newtonian gravity in strange stars based on a density dependent quark mass model

Using a density dependent quark mass (QMDD) model for strange matter, we investigate the effects of non-Newtonian gravity on properties stars and constrain parameters QMDD by employing PSR $\mathrm{J}0740+6620$ tidal deformability GW170817. We find that these observations would rule out existence if are ignored. For current masses ${m}_{u0}=2.16\text{ }\text{ }\mathrm{MeV}$, ${m}_{d0}=4.67\text{ ${m}_{s0}=93\text{ star can exist values parameter ${g}^{2}/{\ensuremath{\mu}}^{2}$ in range $4.58\text{ }{\mathrm{GeV}}^{\ensuremath{-}2}\ensuremath{\le}{g}^{2}/{\ensuremath{\mu}}^{2}\ensuremath{\le}9.32\text{ }{\mathrm{GeV}}^{\ensuremath{-}2}$, $D$ $C$ restricted to $158.3\text{ }\mathrm{MeV}\ensuremath{\le}{D}^{1/2}\ensuremath{\le}181.2\text{ }\mathrm{MeV}$ $\ensuremath{-}0.65\ensuremath{\le}C\ensuremath{\le}\ensuremath{-}0.12$.
