Magnetized Strange Quark Matter In Reconstructed $F(R,T)$ Gravity For Bianchi I And V Universes With Cosmological Constant, Can Aktaş
Turkish Journal of Physics
In this article, we have investigated the behaviors of magnetized strange quark matter distributions for Bianchi I and V universes in reconstructed $f?eft( R,T \right)=\alpha_{1}R+\alpha_{2}f_{3}(T)$ gravity (here $\alpha_{1}$ and $\alpha_{2}$ are constants; $f_{3}(T)$ is an arbitrary function of $T)$. To get solutions of the field equations we have used a deceleration parameter and the equation of state for strange quark matter. The new represented $f(R,T)$ model includes two models of Harko et al. and transforms to general relativity. When $t\to ınfty $, we get the dark energy model ($p=-\rho )$ in reconstructed $f?eft( R,T \right)=\alpha _{1}R+\alpha_{2}f_{3}(T)$ gravity. However, we obtain …

Marder Type Universe With Bulk Viscous String Cosmological Model In $F(R,T)$ Gravity, Sezgi̇n Aygün
Turkish Journal of Physics
In this study, we have investigated homogeneous and anisotropic Marder space-time with bulk viscous string matter distribution in $f(R,T)$ gravity. For this aim we have used the anisotropy feature $(\frac{\sigma_{x}^{x} }{\theta })$ of Marder space-time and a deceleration parameter in two different $f(R,T)$ models. We have obtained bulk viscous matter distribution solutions in $f(R,T)$ gravity. Finally, some kinematical and physical properties are discussed.
