In this paper, we study axially symmetric space-time with strange quark matter attached to string cloud in Rosen's (1973) bimetric theory. It is shown that there is no contribution from strange quark matter, hence vacuum model is presented and studied

The basic objective of this investigation is to explore the impactof a novel gravitational modification, specifically, the$f(\mathcal{G}, \mathbf{T}^2)$ (where $\mathcal{G}:=\mathbf{R}^{2}+R_{\alpha\beta\sigma\varsigma}R^{\alpha\beta\sigma\varsigma}-4R_{\alpha\beta}R^{\alpha\beta}$and...
