【摘要】 <正>We investigate the effects of non-Newtonian gravity on the properties of strange quark stars(QSs) and constrain the parameters of the standard MIT bag model used to describe strange quark matter(SQM) by employing the mass of PSR J0740+6620 and the tidal deformability of GW170817.We find that,for the standard MIT bag model,更多还原
