We present spherically symmetric anisotropic charged strange stars under the framework of $f(R,T)$ gravity. For this we consider that the Lagrangian density is a linear function of $R$ and $T$ where $R$ is the Ricci Scalar and $T$ represents the trace of the energy–momentum tensor. These stars are considered to be built with Strange Quark Matter (SQM) distribution. To describe this SQM distribution inside the stellar bodies, we incorporate the simplest form of phenomenological MIT bag model equation of state (EOS) $p_r=\frac{1}{3}(\rho -4B_g)$, where $p_r$ is the radial pressure, $\rho$ is the energy density and $B_g$ is the bag constant. To determine density and pressure from the Einstein Field Equations (EFE), we use Krori-Barua (KB) metric and using the observed values of mass and radius for strange star candidates $LMCX-4$, we calculate the value of $B_g$ from our model. Comparing the interior metric with exterior Reissner-Nordström metric at the surface, we calculate the unknown parameters incorporating the observed values of the mass and radius, we find that the coupling constant $\chi$ affects the bag value significantly. The model shows consistency with all the physical conditions and presents a viable study to the nature of charged anisotropic massive stellar system.

我们在以下框架下提出球对称各向异性带电的奇异恒星 $F（\mathrm{[R}，Ť）$重力。为此，我们认为拉格朗日密度是$\mathrm{[R}$ 和 $Ť$ 在哪里 $\mathrm{[R}$ 是Ricci Scalar和 $Ť$表示能量动量张量的轨迹。这些恒星被认为是建立在奇怪的夸克物质（SQM）分布的基础上的。为了描述星体内部的SQM分布，我们结合了现象学MIT袋模型状态方程（EOS）的最简单形式$p_{\mathrm{[R}}=\frac{\mathrm{1个}}{3}（\rho -4{乙}_G）$， 在哪里 $p_{\mathrm{[R}}$ 是径向压力， $\rho$ 是能量密度和 ${乙}_G$是袋子常数。为了从爱因斯坦场方程（EFE）确定密度和压力，我们使用Krori-Barua（KB）度量，并使用观测到的质量和半径值作为候选恒星的方法$\mathrm{大号}\mathrm{中号}CX-4$，我们计算的值 ${乙}_G$从我们的模型。将内部度量与表面的外部Reissner-Nordström度量进行比较，我们计算出结合了质量和半径的观测值的未知参数，我们发现耦合常数$\chi$大大影响袋子的价值。该模型显示了与所有物理条件的一致性，并对带电的各向异性大质量恒星系统的性质提出了可行的研究。
