标题： Influence of Charge on Anisotropic Class-one Solution in Non-minimally Coupled Gravity

摘要： 本文研究了与各向异性物质分布相关的带电星体模型，在$f(\mathcal{R},\mathcal{T},\mathcal{Q})$理论中，$\mathcal{Q}=\mathcal{R}_{\phi\psi}\mathcal{T}^{\phi\psi}$。 为此，我们采用这种引力的线性模型作为$\mathcal{R}+\zeta\mathcal{Q}$，其中$\zeta$表示耦合常数。 我们考虑在电磁场存在下的自引力球形几何，并通过使用“嵌入类一”条件和$\mathbb{MIT}$袋模型状态方程来生成修改后的场方程的解。 利用四个不同恒星模型（如 4U 1820-30，SAX J 1808.4-3658，SMC X-4 和 Her X-I）的观测数据（质量与半径）来分析电荷对其物理性质的影响。 最后，检查耦合常数对所得解的可行性、流体静力平衡条件和稳定性的影响。 我们得出结论，所考虑的模型在所有考虑的电荷和$\zeta$值下表现出可行且稳定的行为。 显示英文摘要

摘要： This paper studies charged star models associated with anisotropic matter distribution in $f(\mathcal{R},\mathcal{T},\mathcal{Q})$ theory, where $\mathcal{Q}=\mathcal{R}_{\phi\psi}\mathcal{T}^{\phi\psi}$. For this purpose, we take a linear model of this gravity as $\mathcal{R}+\zeta\mathcal{Q}$, where $\zeta$ represents a coupling constant. We consider a self-gravitating spherical geometry in the presence of electromagnetic field and generate solution to the modified field equations by using the ``embedding class-one'' condition and $\mathbb{MIT}$ bag model equation of state. The observational data (masses and radii) of four different stellar models like 4U 1820-30,~SAX J 1808.4-3658,~SMC X-4 and Her X-I is employed to analyze the effects of charge on their physical properties. Finally, the effect of the coupling constant is checked on the viability, hydrostatic equilibrium condition and stability of the resulting solution. We conclude that the considered models show viable and stable behavior for all the considered values of charge and $\zeta$.
