It introduces a cylindrical model for charged anisotropic fluids without external pressure, extending previous methods to explore new astrophysical and dark matter implications.

Findings

Charge remains non-zero at the cylinder's center.

Models satisfy all energy and stability conditions.

Graphical analysis supports physically reasonable matter distribution.

Abstract

We take charged anisotropic fluid cylinder when there is no external pressure acting on the fluid. This is a cylindrical version of the Krori and Barua's method to explore the field equations with anisotropic fluid. We discuss models with positive matter density and pressure that satisfy all the energy and stability conditions. It is found that charge does not vanish at the center of the cylinder. The equilibrium condition as well as physical conditions are discussed. Further, we highlight the connection between our solutions and the charged strange quark stars as well as with dark matter including charged massive particles. The graphical analysis of the matter variables versus charge is given which indicates a physically reasonable matter distribution.
