In this letter we show that the presence of the long-range Coulomb force in dense stellar matter implies that the total charge cannot be associated with a chemical potential, even if it is a conserved quantity. As a further consequence, the analytical properties of the partition sum are modified, changing the order of the phase transitions and affecting the possible occurrence of critical behaviours. The peculiar thermodynamic properties of the system can be understood introducing a model hamiltonian in which each charge is independently neutralized by a uniform background of opposite charge.

  1. Bayesian analysis of the shear modulus in the neutron-star crust

    astro-ph.HE 2026-06 unverdicted novelty 4.0 of 10

    Bayesian modeling with informed priors reduces uncertainties in neutron-star crust shear properties, predicting torsional mode frequencies of 20-50 Hz compatible with observations.

  2. Crust (Unified) Tool for Equation-of-state Reconstruction (CUTER) v2

    astro-ph.HE 2025-06 accept novelty 4.0 of 10

    CUTER v2 reconstructs the missing or inconsistent low-density crust of arbitrary neutron-star equations of state, producing unified EoSs whose global properties match original models to within about one percent.
