我们目前的工作的目的是研究静态各向异性相对论杂化紧凑型星的一些新特征，该恒星由内核中的奇怪夸克物质（SQM）组成，在地壳中的正常baryonic物质分布中。在这里，我们应用现象学MIT袋模型的最简单形式的状态方程$ p_q = \ frac {1} {3}（ρ_Q -4B_G）$来将恒星内部内部奇异夸克物质的密度和压力相关联，而radial压力密度和由于baryonic linection $ precection $ precection $ prec_ $ precection $。为了获得爱因斯坦场方程的解，我们使用了Tolman-Kuchowicz {\ em ansatz} [Tolman，Phys Rev 55：364，1939; Kuchowicz，Acta Phys Pol 33：541，1968]，并从某些物理条件中进一步推导了任意常数。在这里，我们在图形和分析上详细检查了我们提出的模型，以了解物理上合理的条件。特别是，对于此调查，我们已经报告了紧凑的对象她的$ x-1 $ [mass = $（0.98 \ pm 0.12）m _ {\ odot} $;半径= $ 8.1 _ { - 0.41}^{+0.41} $ km在我们的论文中，作为一个奇怪的夸克星候选人。为了检查我们建议模型的身体有效性和稳定性，我们在分析和图形上进行了各种物理测试，即应用力的动力平衡，能量条件，紧凑型因子和表面红移等。最后，我们发现我们目前的模型发现了对奇怪的Quark Stars（SQS）的所有必要的物理需求，并且可以满足现实性的所有模型）（sqs sqs）。
The purpose of our present work is to investigate some new features of a static anisotropic relativistic hybrid compact star composed of strange quark matter (SQM) in the inner core and normal baryonic matter distribution in the crust. Here we apply the simplest form of the phenomenological MIT bag model equation of state $p_q = \frac{1}{3}(ρ_q - 4B_g)$ to correlate the density and pressure of strange quark matter within the stellar interior, whereas radial pressure and matter density due to baryonic matter are connected by the simple linear equation of state $p_r = αρ- β$. In order to obtain the solution of the Einstein field equations, we have used the Tolman-Kuchowicz {\em ansatz} [Tolman, Phys Rev 55:364, 1939; Kuchowicz, Acta Phys Pol 33:541, 1968] and further derivation of the arbitrary constants from some physical conditions. Here, we examine our proposed model graphically and analytically in detail for physically plausible conditions. In particular, for this investigation, we have reported on the compact object Her $X-1$ [Mass=$(0.98 \pm 0.12)M_{\odot}$; Radius= $8.1_{-0.41}^{+0.41}$ km] in our paper as a strange quark star candidate. In order to check the physical validity and stability of our suggested model, we have performed various physical tests both analytically and graphically, namely, dynamical equilibrium of applied forces, energy conditions, compactness factor, and surface redshift etc. Finally, we have found that our present model meets all the necessary physical requirements for a realistic model and can be studied for strange quark stars (SQS).
