论文摘要
在准粒子模型中研究了奇怪的夸克恒星的性能。考虑到化学平衡和电荷中立性，获得了$（2+1）$ - 味的夸克物质的EOS。我们说明了来自两个方面的约束的参数空间：一个基于PSR J $ 0740+6620 $和GW $ 170817 $的天文学结果，另一个是基于紧凑型星的理论研究所提出的约束，以确保EOS确保EOS确保Tidal Dromantosibality $ $ $ $ \ varlambda_ {1.4} = 190^{+390} _ { - 120} $，并在$ 1.97〜m _ {\ odot} $上支持最大质量。发现两种类型的约束都不能限制可靠区域中准粒子模型的参数空间，因此我们得出结论，小型紧凑型星不能是奇怪的夸克恒星。
The properties of strange quark stars are studied within the quasi-particle model. Taking into account the chemical equilibrium and charge neutrality, the EOS of $ (2+1) $-flavor quark matter is obtained. We illustrate the parameter spaces with constraints from two aspects: the one is based on the astronomical results of PSR J$ 0740+6620 $ and GW$ 170817 $, and another is based on the constraints proposed from the theoretical study of compact star that the EOS must ensure the tidal deformability $ \varLambda_{1.4}=190^{+390}_{-120} $ and support a maximum mass above $ 1.97~M_{\odot} $. It is found that the both types of constraints can not restrict the parameter space of quasi-particle model in a reliable region and thus we conclude that the small compact star cannot be strange quark star.
