In the present work we study the equation of state for asymmetric hadronic matter, to be applied in neutron star structure calculation. The delta-rich hadronic stellar matter condensate is studied in the context of mean-field approximation in an exte

This work shows results for the EXO 0748-676 neutron star structure obtained with the use of a phenomenological quark matter description by taking into account a quark interaction, and observing the asymptotic freedom and the confinement characterist

Recently reported massive compact stars ( M ∼ 2 M ⊙ ) have provided strong constraints on the properties of the ultradense matter beyond the saturation nuclear density. Therefore, realistic quark or hybrid star models must be compatible with thes

The color–flavor locked (CFL) phase is believed to be the fundamental state of strange quark matter (SQM) at high densities. The CFL phase is a color superconductor composed of pairs of u, d and s quarks, with no electrons, forming a Bose condensat

In this work we have obtained the equation of state to the highly asymmetric dense stellar matter, using the nonlinear Walecka model in the mean field approximation. We discussed the implication of changes in coupling constant of the delta baryonic r

In the present work we determine the equation of state of delta‐resonance‐rich stellar matter and discuss the effects of the baryon‐meson coupling constants on the delta population in the stellar medium. We extended the non‐linear Walecka (NL

The static spherically symmetric quark star structure is calculated by using an equation of state which takes into account the superconducting Color-Flavor Locked (CFL) phase of the strange quark matter. Some fundamental aspects of QCD (asymptotic fr

We study the nuclear matter properties in the regime of high temperatures using a relativistic mean‐field theory. Contrasting with the usual linear Walecka model [1], we include the σ‐ω meson coupling [2] in order to investigate the role of thi
