It is shown that for a timelike boundary hypersurface of zero thickness, the generalised matching conditions across this surface in EGB gravity are satisfied. A sufficient condition is that the Israel-Darmois conditions are valid. Therefore it is possible to generate a complete stellar model in EGB gravity. The interior matches to the exterior higher dimensional charged Boulware–Deser spacetime with cosmological constant. The barotropic radial pressure has to vanish at the boundary of the star which is also the case in general relativity.19 penJunction conditionsDifferential geometryEinstein-Gauss-Bonnet gravityStars01 Mathematical Sciences02 Physical SciencesNuclear & Particles Physics49 Mathematical sciences51 Physical sciencesArticle2024-08-1010.1088/1361-6382/acd29c
