Anisotropic strange quintessence stars in \(f(R, G)\) gravity. (English) Zbl 07819426
Summary: This paper is devoted to formulate a new model of quintessence anisotropic compact stars in the modified \(f(R, G)\) gravity. Dynamical equations in modified theory consisting of anisotropic fluid along with quintessence field have been evaluated by adopting analytical
solution of Krori-Barua. In order to determine the unknown constraints of Krori-Barua metric observational data of different stars, \(4U\) 1820-30, Her \(X-1\) \(SAX\) \(J18083658\) has been taken into account. To solve the dynamical equations Starobinsky-like model, \(f(R, G) = R + \lambda R^2 + G\) of modified gravity has been used. The outcome of the results depicts that all the examined celestial bodies are free from central singularity and are physically stable. Different physical parameters, such as energy density, energy conditions, evolution of quintessence and compactness factor, have been reviewed in detail.
