Strange Quark Stars in 4D Einstein–Gauss–Bonnet Gravity

Abstract The existence of strange matter in compact stars may give rise to striking outcomes the various physical phenomena. As an alternative neutron stars, a new class called should exist if hypothesis is true. In this paper, we investigate possible construction quark phases based on MIT bag model. We consider scenarios which have no crusts. Then apply two types equations state quantify mass–radius diagram for static star models, performing numerical calculation modified Tolman–Oppenheimer–Volkoff context 4D Einstein–Gauss–Bonnet (EGB) gravity. It worth noting that GB term gives nontrivial contribution gravitational dynamics limit D ? 4. However, claim resulting theory one pure gravity has been cast doubt several grounds. Thus, begin our discussion by showing regularized EGB equivalent action as novel spherically symmetric spacetime. also study effects coupling constant ? properties constructed including compactness and criterion adiabatic stability. Finally, compare results those obtained from standard general relativity.
