Anisotropic extensions of isotropic Finch-Skea metric in the charged modified gravity

In this study,we explore the Finch-Skea perfect fluid solution and extend its domain to three distinct anisotropic interior models within the framework of the f(R,T)theory,incorporating the influence of an electromagnetic field.We assume a static spherical spacetime initially coupled with an isotropic matter distribution.We then introduce a Lagrangian corresponding to an additional gravitating source,taking into account its role in inducing pressure anisotropy within the original fluid source.By deriving the field equations for the combined matter setup,we applied a radial component transformation,which yielded two distinct systems of equations.In addition,we consider a charged exterior spacetime to determine the three constants associated with the Finch-Skea solution at the boundary.Our findings suggest that under certain parametric choices,all three resulting models exhibited physical relevance within this modified theory.
