Effects of Temperature on Dense Matter with Neutrino Trapping

  • A chiral hadronic model is applied to the investigation of the influences of temperature on the properties of dense matter with neutrino trapping.Our results show that the proton fraction of the npeνe system is less sensitive to the variation of temperature than the npe one.The energy densities of both systems increase with temperature.Moreover,the maximum masses and Kepler frequency of protoneutron stars decrease when temperature increases.

Abstract: A chiral hadronic model is applied to the investigation of the influences of temperature on the properties of dense matter with neutrino trapping.Our results show that the proton fraction of the npeνe system is less sensitive to the variation of temperature than the npe one.The energy densities of both systems increase with temperature.Moreover,the maximum masses and Kepler frequency of protoneutron stars decrease when temperature increases.
