Formation of cylindrical gravastars in modified gravity

In this paper, we analyze a few physical characteristics of gravastar with cylindrical geometry in $f(R,T)$ theory, where $R$ is the Ricci scalar and $T$ trace energy-momentum tensor. The generally considered to be substitute black hole three different regions. present work, examine formulation gravastar-like structures theory. By using Darmois Israel matching conditions, formulate mass function thin shell. We calculate gravastar, particular, entropy within shell, proper length intermediate shell as well energy
