摘要:We have constructed a new table of the nuclear equation of state (EOS) for numerical simulations of core-collapse supernovae. The EOS of uniform nuclear matter has been calculated with the cluster variational method based on the AV18 and UIX potentials. For non-uniform nuclear matter, we have adopted the Thomas-Fermi approximation following the method by Shen, Toki, Oyamatsu and Sumiyoshi in order to obtain the EOS of inhomogeneous phase in a self-consistent manner. Then, the obtained free energy and related thermodynamic quantities are tabulated in wide ranges of density, temperature, and proton fraction. 
In this talk, we systematically compare the thermodynamic quantities of the present EOS with those of the Shen EOS. Furthermore, we discuss the properties of our EOS in core-collapse supernova simulations.
