  The inner crust of a neutron star consists of nuclei immersed in a superfluid
neutron liquid. As these nuclei move through the fermionic medium they bring it
into motion as well. As a result their mass is strongly renormalized and the
spectrum of the ion lattice vibrations is significantly affected. Consequently
we predict that the specific heat and the lattice thermal energy of the Coulomb
crystal at these densities are noticeably modified.
