Özet
The study is conducted for investigation of a new solution for stellar objects in κ(R, T) theory. We investigate whether Krori–Barua model produces valid results in κ(R, T) theory. We attain field equations through Krori–Barua metric form related with geometry of inner space. From field equations, we obtain all unknown matter components κ(T) = 8 πG− λT in the theory. Constructed model is considered with some class of compact stars such as 4 U1820 − 30 , SAXJ1808.4 − 3658 , and HerX− 1 . To prove physical stability of the constructed model, we investigate both normal and effective matter form behaviors by way of some physical conditions. It is found that all conditions are valid for effective matter. Therefore, this study reveals consistency of both the compact star model and the gravitation theory. But a remarkable point is that normal matter has to face some problems in the κ(R, T) theory.
