Proto-neutron star in generalized thermo-statistics

ABSTRACT. The proto-neutron star (PNS) is investigated for the first time in the generalized thermo-statistics. The subextensive entropy for the power-law index q>1 leads to much lower temperature in a core of PNS than the Clausius extensive entropy. Consequently, we can see a clear difference between the mass-radius relation of PNS in the standard (q=1.0) and generalized (q=1.3) thermo-statistics. The result is essentially due to the effect of gravitation that is consistent with the subextensivity of the generalized entropy.
