For the case with first-order phase transitions, compact stars in EiBI gravity with a positive coupling parameter $\\kappa $ exhibit a finite region with constant pressure, which is absent in general relativity. However, for the case with a negative $\\kappa $, an equilibrium stellar configuration cannot be constructed. Hence, EiBI gravity seems to impose stricter constraints on the microphysics of st","authors_text":"L.-M. Lin, P. T. Leung, Y.-H.
