Anisotropic strange compact stars in Krori-Barua spacetime under f (R, G) gravity

A. R. Athar et al.

Summary: This paper elaborates on the matter distribution and different characteristics of anisotropic compact stars in f (R, G) gravity background. By calculating physical quantities such as energy density, radial pressure, and tangential pressure using different models, the physical behavior of compact stars is explored. The results of measurements on anisotropy, energy conditions, and stability aspects of the models are presented using graphical techniques, and the behavior of the six stars under the (G) model parameter is discussed.
