Abstract

We investigate stability bound of neutron stars based on Eddington-inspired Born Infeld (EiBI) theory of gravity using two kind of equations of states i.e., a non-interacting neutron gas and interacting baryon gas within relativistic mean field model to describe the core of the corresponding neutron stars. The stability bound is investigated by using the concept of configurational entropy where the spatial complexity of energy density from the solution of stellar effective equations which is transformed in momentum space, are used. We use the same argument as the one used in Ref. [1] that the stability and instability region is given by a local minimum between configuration entropy (CE) with respect to central density. We obtained similar result to the one of general relativity theory [1] that the inverse scaling relation between mass and CE still holds for EiBI theory.
