Nonextensive thermodynamics with finite chemical potentials and protoneutron stars

We derive the nonextensive thermodynamics of an ideal quantum gas composed by bosons and/or fermions with finite chemical potentials. We find agreement with previous works when $μ\le m$, and some inconsistencies are corrected for fermions when $μ> m$. This formalism is then used to study the thermodynamical properties of hadronic systems based on a Hadron Resonance Gas approach. We apply this result to study the protoneutron star stability under several conditions.
