In this paper, we investigate the charged static spherically symmetric models in [Formula: see text] theory of gravity. We consider a linear equation of state (EoS) in the background of anisotropic matter configuration. We formulate the modified field equations and implement Durgapal transformation to examine the gravitational nature of compact stellar objects. For this purpose, we choose a specific gravitational potential and electric charge intensity to analytically solve the set of field equations. We generate three special cases of solutions for specific parametric values of [Formula: see text] appearing in the expression of gravitational potential. The evolution of physical observables, such as energy density, anisotropy parameter, radial and tangential pressures and electric field intensity, are presented in all cases. Via physical analysis, it is observed that the solution of charged compact spheres satisfies acceptability criteria, models are well behaved, and depict stability and consistency in accordance with [Formula: see text] gravity for generated models.

Durgapal 变换下 f(R) 重力的各向异性带电现实模型

在本文中,我们研究了[公式:见正文]引力理论中的带电静态球对称模型。我们在各向异性物质配置的背景下考虑线性状态方程(EoS)。我们制定了修改后的场方程并实施了杜尔加帕变换来检查致密恒星物体的引力性质。为此,我们选择特定的引力势和电荷强度来解析求解这组场方程。对于出现在引力势表达式中的 [公式:见正文] 的特定参数值,我们生成了三种特殊情况的解。在所有情况下都呈现了物理可观测量的演变,例如能量密度、各向异性参数、径向和切向压力以及电场强度。通过物理分析,
