Electromagnetic effects on cylindrical gravastar-like strings in f(R, T, RσηTση) gravity

Abstract

The purpose of this paper is to investigate the non-singular solutions of gravitationally vacuumed condensate star in the realm of the f(R, T, Q) theory, where Q = RσηTση. The three-layered gravastar structure has been constructed in the cylindrical spacetime under the effects of electromagnetism in the modified theory. Furthermore, we have studied the effects of electromagnetism on the effective matter, which involves the perfect fluid and isotropic pressure in it. To gain this objective, we consider the cylindrical spacetime and evaluate the three regions mathematically. The metric coefficients are calculated independently for each region. To match the region I and II at a hypersurface, the junction conditions have been calculated. To figure out the dependency of the thickness of shell on different physical features of gravastar, we interpret it graphically as well as mathematically. Subsequently, the noticeable facts are accomplished.
