STOS + hyperons and pions (Sigma potential 0 MeV)

Abstract

This table contains the EoS of C. Ishizuka et al. [IOTSJ_2008]. It is an extension of the EoS by H. Shen, F. Yang, H. Toki, K. Oyamatsu, and K. Sumiyoshi [STOSP_1998,STOSN_1998] including hyperons and pions using a non-linear relativistic mean-field model with the TM1 parametrization [STNP_1994] of the effective nuclear interaction. Hyperonic couplings are fixed by SU(3)-symmetry and the single particle potentials in nuclear matter at saturation density. This is the version with U_{Sigma N} = 0 MeV. Non-uniform nuclear matter is calculated in the single-nucleus Thomas-Fermi approximation with parametrized density distributions in spherical Wigner-Seitz cells. Only neutrons, protons, alpha particles and a single heavy nucleus are considered. The present table was taken from the website aspht1.ph.noda.tus.ac.jp/ishizuka of C. Ishizuka.
