New ab initio constrained extended Skyrme equations of state for simulations of neutron stars, supernovae, and binary mergers: II. Thermal response in the suprasaturation density domain
Context. Numerical simulations of core-collapse supernovae, mergers of binary neutron stars, and the formation of stellar black holes, using standard Skyrme interactions, have established clear correlations between the evolution of these processes, the characteristics of hot comp

An extended thermal pressure equation of state for sodium fluoride
A PVT equation of state has been determined for sodium fluoride with a range of validity between 12 and 950 K in temperature and 0 and 25 GPa in pressure. This equation of state is based on a fourth-order Birch–Murnaghan expression for isothermal compression and a Mie–Grüneisen–Debye model for thermal pressure.
