论文摘要
我们研究了夸克恒星（QSS）的结构，这些结构采用了三种味道中性电荷和固定的奇怪夸克质量$ m_s $，在恒星内采用同质限制物质。我们探讨了最近提出的能量摩托明平方重力（EMSG）中特定类别QSS的内部结构和物理特性。此外，我们使用QCD动机的EOS获得了QS的Mass-Radius $（M-R）$和群众中心的能量密度$（M-ρ_C）$。根据自由参数$α$的存在和不存在，研究了EMSG中QSS的最大质量。此外，星的稳定性取决于条件$ \ frac {d m} {dρ_c}> 0 $。我们观察到，对EMSG的考虑对QSS结构有特定的贡献。
We study the structure of quark stars (QSs) adopting homogeneously confined matter inside the star with a 3-flavor neutral charge and a fixed strange quark mass $m_s$. We explore the internal structure, and the physical properties of specific classes of QSs in the recently proposed energy-momentum squared gravity (EMSG). Also, we obtain the mass-radius $(M-R)$ and mass-central energy density $(M-ρ_c)$ relations for QS using the QCD motivated EoS. The maximum mass for QSs in EMSG is investigated depending on the presence and absence of the free parameter $α$. Furthermore, the stability of stars is determined by the condition $\frac{d M}{d ρ_c}>0$. We observe that consideration of the EMSG has specific contributions to the structure of QSs.
