Description
We show how the mass and self-coupling of the QCD axion change at finite temperature and baryon density within the framework of Nambu-Jona-Lasinio model. We mainly focus on the effect of the chiral symmetry restoration and two flavor color-superconductivity on the axion properties by taking into account the charge neutrality constraint. We find that both the axion mass and self-coupling become smaller in the thermal and dense medium. The possible influence of the axion on the cooling rates of the proto-neutron stars is discussed.
