标题： Influence of Charge on Decoupled Anisotropic Spheres in $f(G,T)$ Gravity

摘要： 在本文中，我们通过引力解耦方法，在$f(G,T)$理论中发展了两种各向异性解，用于静态自引力球形结构在电磁场存在下的情况，其中$G$和$T$分别表示高斯-博内特项和能量-动量张量的迹。 具有各向同性种子区的额外源负责在时空中产生各向异性。 通过在径向分量中使用最小几何变形，将场方程系统解耦为两个数组。 第一组描述各向同性区域，而第二组表示各向异性系统。 利用 Krori-Barua 时空的度规系数来提取第一组的解，而对额外源的径向和时间分量的两个约束条件则得到相应的两个解。 最后，我们研究了电荷和解耦参数对所获得解的物理可行性和稳定性的影响。 我们得出结论，这种修改理论中的结果解表明更可行和稳定的结构。 显示英文摘要

摘要： In this paper, we develop two anisotropic solutions for static self-gravitating spherical structure in the presence of electromagnetic field through gravitational decoupling approach in $f(G,T)$ theory, where $G$ and $T$ denote the Gauss-Bonnet term and trace of the energy-momentum tensor, respectively. The extra source with isotropic seed sector is responsible for generating anisotropy in the spacetime. The system of field equations is decoupled into two arrays by using minimal geometric deformation in the radial component. The first set portrays the isotropic regime whereas the second set represents the anisotropic system. The metric coefficients of the Krori-Barua spacetime are employed to extract solution of the first set while two constraints on the radial and temporal components of the extra source yield the corresponding two solutions. Finally, we investigate the influence of charge and decoupling parameter on the physical viability and stability of the obtained solutions. We conclude that the resulting solutions in this modified theory indicate more feasible and stable structures.
