我们研究了介质效应在奇异夸克物质上的影响及其对致密星结构性质的后果。在本研究中，麻省理工学院袋模型状态方程中的袋常数被重新表述为夸克化学势的函数。通过施加博德默 - 维滕稳定性判据，利用重子能量评估来约束参数空间。然后求解托尔曼 - 奥本海默 - 沃尔科夫方程以获得最大质量 - 半径构型。分析表明化学势增加导致袋常数有效值减小，状态方程变硬，最大恒星质量相应增加。此外，我们研究了潮汐洛夫数和潮汐形变率对化学势的依赖性。结果表明，对于所选参数集，引力波170817事件的约束条件，即 $\Lambda < 800$ 始终得到满足。本文试图确定化学势 $(\mu)$ 如何影响奇异星的最大质量和潮汐形变率。
英文摘要
We investigate the influence of medium effects on strange quark matter and their consequences for the structural properties of compact stars. In this study, the bag constant, in the MIT bag model equation of state, is reformulated as a function of the chemical potential of quark. Imposing the Bodmer-Witten stability criterion, the parameter space is constrained by evaluating the energy per baryon. The Tolman-Oppenheimer-Volkoff equations are then solved to obtain the maximum mass-radius configurations. Our analysis shows that an increase in chemical potential leads to a reduction in the effective value of bag constant, resulting in a stiffer equation of state and correspondingly higher value of maximum stellar mass. Furthermore, we examine the chemical potential dependence of the tidal Love number and tidal deformability along with their corresponding finite surface density corrections. The results demonstrate that, for the chosen set of parameters, the constraint from the GW170817 event, namely $Λ< 800$, is consistently satisfied. In this paper, we have tried to establish how chemical potential $(μ)$ affects the maximum mass and tidal deformability of strange stars.
