In this study, it is aimed to investigate the Krori–Barua type compact stars within the scope of [Formula: see text] theory. In this context, first, the field equations are obtained by considering the [Formula: see text] model. Interestingly, the model offers chance to attain all components of matter without any restrictions. In addition, data sets from LMC X-4, EXO 1785-248 and Cen X-3 are used to analyze physical stability of the solutions. It is obtained that all conditions such as causality and stability. which indicate consistency between compact objects and [Formula: see text] theory are valid for the constructed model. We obtained that small values of [Formula: see text] in the [Formula: see text] function show significant effect on the consistency of the star models. Therefore, different [Formula: see text] values are considered for each star data set when graphing the physical states. Finally, necessary quantities of the model are defined, compared with the considered stars and discussed in detail.
