Crust-core transition of a neutron star: Effects of the symmetry energy and temperature under strong magnetic fields

“…We may, therefore, expect that the effect of a strong magnetic field on the transition will also depend on the symmetry energy, since the magnetic field is sensitive to the amount of protons: the smaller the proton density, the stronger are the effects. In previous studies [12,13], this aspect has already been identified.…”

“…Above B * ∼ 10 3 (B ∼ 5 × 10 16 G), the AMM has a non-negligible effect and, therefore, we will essentially restrict ourselves to values below that number. As discussed in [12,13], the spinodal section shows a complex structure and bands of instability with large isospin asymmetry appear associated with the filling of the different Landau levels. As a result for low temperatures, the β-equilibrium EoS crosses the spinodal section several times, defining the region of instability referred before, see Fig.…”

“…Conclusion: We have analyzed how the effects of a strong magnetic field on the neutron star crust, previously studied in [12,13], are affected by the density dependence of the symmetry energy of the EoS, and by the temperature of the crust, within a RMF description of npe and np matter. At T = 0, the crust-core transition was obtained from the dynamical spinodal with AMM, and at finite temperatures, from the thermodynamical spinodal, excluding the AMM, which is justified since only magnetic fields below 5 × 10 16 G are considered.…”

“…In [12,13], the effect of strong magnetic fields on the inner crust of neutron stars was discussed within a relativistic mean-field (RMF) model, and several interesting results were obtained. It was found that the inner crust is more complex in the presence of strong magnetic fields, and alternating regions of clusterized and non-clusterized matter appear above the B = 0 crust-core transition density.…”

“…The increase of the inner crust due to magnetic field effects found in Refs. [12,13] could validate the crustal contribution to the description of the glitch mechanism.…”
