Abstract

AbstractThe density dependent relativistic hadron field (DDRHF) theory is introduced with various forms of the density dependence of the nuclear interaction to study the A matter in the β ‐equilibrium. Several new parametrizations are extracted from the Dirac‐Brueckner‐Hartree‐Fock (DBHF) calculations. We have compared and analysed high density extrapolations of A matter properties and shown that the choice of the density dependence has important effects on the structure of compact stars.
