Query: A comparative study between EGB gravity and GTR by modelling compact
  stars   In this paper we utilise the Krori-Barua ansatz to model compact stars within
the framework of Einstein- Gauss-Bonnet (EGB) gravity. The thrust of our
investigation is to carry out a comparative analysis of the physical properties
of our models in EGB and classical general relativity theory.
