Construction of Charged Cylindrical Gravastar-like Structures

Abstract

In this work, we extend the work of gravastars to analyze the role of electromagnetic field in $f(R,T)$ gravity. We consider the irrotational cylindrically symmetric geometry and established the $f(R,T)$ field equations and conservation laws. After considering charged exterior geometry, the mathematical quantities for evaluating Israel junction conditions are being calculated. The mass of the gravastar-like cylindrical structure is calculated through the equations of motion at the hypersurface in the presence of an electromagnetic field. The behavior of electric charge on the length of the thin shell, energy content, and entropy of gravastar is being studied graphically. We concluded that charge has an important role in the length of the thin shell, energy content, and entropy of gravastar.
