Within this nucleon-meson model, a chiral density wave in neutron star cores is only stable for equations of state too soft to support observed two-solar-mass pulsars, predicting isotropic cores.

abstract
We investigate the influence of spatially inhomogeneous chiral symmetry-breaking condensates in a magnetic field background on the equation of state for compact stellar objects. After building a hybrid star composed of nuclear and quark matter using the Maxwell construction, we find, by solving the Tolman-Oppenheimer-Volkoff equations for stellar equilibrium, that our equation of state supports stars with masses around 2 $M_\odot$ for values of the magnetic field that are in accordance with those inferred from magnetar data. The inclusion of a weak vector interaction term in the quark part allows one to reach 2 solar masses for relatively small central magnetic fields, making this composition a viable possibility for describing the internal degrees of freedom of this class of astrophysical objects.

How neutron star properties disfavor a nuclear chiral density wave
Within this nucleon-meson model, a chiral density wave in neutron star cores is only stable for equations of state too soft to support observed two-solar-mass pulsars, predicting isotropic cores.
