Warm dense matter and cooling of supernovae remnants

Understand

We study the thermal effects on the nuclear matter (NM) properties such as binding energy, incompressibility, free symmetry energy and its coefficients using NL3, G3 and IU-FSU parameter sets of relativistic mean-field models.

• These models being consistent with the properties of cold NM, have also been used to study the effect of temperature by incorporating the Fermi function.
• The critical temperature for the liquid-gas phase transition in the symmetric NM is found to be 14.60, 15.37 and 14.50 MeV for NL3, G3 and IU-FSU parameter sets respectively, which is in excellent agreement with previous theoretical and experimental studies.
• We inspect that the properties related to second differential coefficient of the binding energy and free symmetry energy at saturation density ( i.e.
