In recent days gravastar has been a very lucrative alternative to black holes, as it does not suffer from the singularity problem as well and it is based on sound physical grounds. Modified Symmetric teleparallel equivalent of gravity also has seen quite a few successes in recent years both in cosmology as well as in astrophysical objects like black holes and wormholes. In this paper, we have considered the charged gravastar in f (Q) formulation and have solved it fully analytically and found various physical characteristics like energy density, entropy and EoS for the gravastar. We have used the Israel junction condition to make some phenomenological predictions regarding the potential of the thin shell around the gravastar. We have also studied the deflection of the angle caused by the gravastar. Finally, we conclude by noting how future radio telescopes could detect the gravastar shadow and how can one distinguish it from the black hole event horizon. • We have considered the charged gravastar in f(Q) gravity. • The physical characteristics like energy density, entropy and EoS for the gravastar are derived analytically. • The Israel junction condition is used to make some phenomenological predictions of the thin shell around the gravastar. • We have also studied the deflection of the angle caused by the gravastar. • We conclude by noting how future radio telescopes could detect the gravastar shadow.

In this paper, we generate an exact anisotropic gravastar model using gravitational decoupling technique through minimal geometric deformation in the framework of f (ℜ , T 2) gravity. This novel model explains an ultra-compact stellar configuration whose internal region is smoothly matched to the exterior region. The developed stellar model satisfies some of the essential characteristics of a physically acceptable model such as a positive monotonically decreasing profile of energy density from the center to the boundary and monotonically decreasing behavior of the pressure. The anisotropic factor and Schwarzschild spacetime follows physically acceptable behavior. We find that all the energy bounds are satisfied except strong energy condition inside the ultra-compact stellar structure for the coupling constant of this theory, which is compatible with the regularity condition. • We generate an exact anisotropic gravastar model by gravitational decoupling method. • Developed stellar model satisfies essential features of a physically acceptable model. • All the energy bounds are satisfied except strong energy condition inside the ultra-compact stellar structure.
