We present a methodical study of the thermal and nuclear properties for the hot nuclear matter using relativistic-mean field theory. We examine the effects of temperature on the binding energy, pressure, thermal index, symmetry energy, and its derivative for the symmetric nuclear matter using temperature-dependent relativistic mean-field formalism for the well-known G2^⁎ and recently developed IOPB-I parameter sets. The critical temperature for the liquid-gas phase transition in an asymmetric nuclear matter system has also been calculated and collated with the experimentally available data. We investigate the approach of the thermal index as a function of nucleon density in the wake of relativistic and non-relativistic formalism. The computation of neutrino emissivity through the direct Urca process for the supernovae remnants has also been performed, which manifests some exciting results about the thermal stabilization and evolution of the newly born proto-neutron star. The central temperature and the maximum mass of the proto-neutron star have also been calculated for different entropy values.

我们使用相对论平均场理论对热核物质的热和核特性进行了有条不紊的研究。我们使用众所周知的 G2 ^{⁎ 的}温度相关相对论平均场形式来研究温度对对称核物质的结合能、压力、热指数、对称能及其导数的影响以及最近开发的 IOPB-I 参数集。还计算了非对称核物质系统中液-气相变的临界温度，并将其与实验可用数据进行了比较。我们在相对论和非相对论形式主义之后研究了热指数作为核子密度的函数的方法。还通过直接乌卡过程计算了超新星残骸的中微子发射率，这显示了关于新生原中子星热稳定和演化的一些令人兴奋的结果。还计算了不同熵值的原中子星的中心温度和最大质量。
