Abstract We obtain an exact spherically symmetric and magnetically charged black hole solution in 4D Einstein-Gauss-Bonnet gravity coupled with rational nonlinear electrodynamics. The thermodynamics of our model is studied. calculate the Hawking temperature heat capacity hole. phase transitions occur point where possesses extremum. show that holes are thermodynamically stable at some range even...

Abstract In the present paper we investigate structure of relativistic stars in 4D Einstein-Gauss-Bonnet gravity. The mass-radius relations are obtained for realistic hadronic and strange quark star equations state, a wide range Gauss-Bonnet coupling parameter ?. Even though deviations from general relativity nonzero values ? can be large enough, they still comparable with variations due to dif...

Abstract An alternative gravity theory that has attracted considerable attention recently is the novel four-dimensional Einstein–Gauss–Bonnet (4EGB) gravity. This idea was proposed to bypass Lovelock’s theorem and permit nontrivial higher curvature effects on local In this approach, Gauss–Bonnet (GB) coupling constant $$\alpha $$ <mml:mi...
