Compact relativistic geometries in f(R,G) gravity

One of the possible potential candidates for describing universe's rapid expansion is modified gravity. In framework theory gravity $f(R,G)$, present work features materialization anisotropic matter, such as compact stars. Specifically, to learn more about physical behavior stars, radial, and tangential pressures well energy density six stars namely $Her X-1$, $SAXJ1808.4-3658$, $4U1820-30$, $PSR J 1614 2230$, $VELA $Cen X-3$ are calculated. Herein, $f(R,G)$ disintegrated into two parts i.e. $\tanh$ hyperbolic $f(R)$ model three different $f(G)$ model. The study focuses on graphical analysis wherein stability aspects, conditions, measurements mainly addressed. Our calculation revealed that, positive value parameter n $f(G)$, all behave normally.
