This work aims to investigate the behaviour of compact stars in background f ( R , T ) $f(R, T)$ theory gravity. For current work, we consider Krori-Barua metric potential i.e., ν r = B 2 + C $\nu (r)= Br^2+C$ and λ A $\lambda Ar^2$ where, $A, B$ are constants. We use matching conditions spherically symmetric space-time with Schwarzschild solution as an exterior geometry examine physical stella...
