Abstract: | |||||
The equation of state of the newborn neutron star matter with
untrapped neutrinos is calculated with the AV18 potential
along isentropic paths. The same calculations are done with the
AV14 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.
