摘要：
The equation of state of the newborn neutron star matter with untrapped neutrinos is calculated with the AV(18) potential along isentropic paths. The same calculations are done with the AV(14) potential for the sake of comparison. Temperature-density correlation, proton fraction, adiabatic index, and the velocity of sound are also obtained at different entropies. It is shown that the proton fraction (adiabatic index) increases (decreases) by increasing entropy. We have shown that our calculated equations of state obey the causality condition. The results are compared with those of others in the literature.
