Abstract
The properties of strange quark stars are studied within the quasi-particle model. Taking into account chemical equilibrium and charge neutrality, the equation of state (EOS) of (2+1)-flavor quark matter is obtained.
We illustrate the parameter spaces with constraints from two aspects: one is based on the astronomical results of PSR J0740 + 6620 and GW 170 817, and the other is based on the constraints proposed from the theoretical study of a compact star that the EOS must ensure the tidal deformability A₁.₄ = 190⁺³⁹⁰₋₁₂₀ and support a maximum mass above 1.97 M. It is found that neither type of constraints can restrict the parameter space of the quasi-particle model in a reliable region and thus we conclude that the low mass compact star cannot be a strange quark star.
