Abstract

The core crust transition density \({{\rho }_{{\text{t}}}}\) and core crust transition pressure \({{P}_{{\text{t}}}}\) of neutron stars are analyzed with the thermodynamical approach using finite range effective interaction for two different splittings of exchange strength parameters. The role of density derivatives of symmetry energy on \({{\rho }_{{\text{t}}}}\) and \({{P}_{{\text{t}}}}\) are studied and it is found that reducing the effect of slope, the curvature of symmetry energy dominates the variation of transition density. The results are compared with various models quoted in the literature.
