Description

Employing a phenomenological nucleon-meson model, we study the possible existence of a chiral density wave in neutron star matter. We impose charge neutrality and β-equilibrium, extending previous works that studied isospin-symmetric nuclear matter. We find that the chiral density wave is energetically preferred in a region of our parameter space that predict a very soft equation of state. In this parameter regime, the maximum neutron star mass does not meet astrophysical constraints. Therefore, the model predicts that such a phase is unlikely to be found in the interior of neutron stars.
