Abstract
This table represents the zero temperature and β-equilibrium EoS by Akmal, Pandharipande and Ravenhall using variational techniques [APRP_1998], interaction A18 + δv + U IX∗.The transition to the pion condensed phase at high densities is handled as a first order phase transition with two homogeneous phases following a Maxwell construction of constant pressure and baryon number chemical potential across the transition, see [DDFG_2025] for a discussion. The two homogeneous phases are described within the framework of Constantinou et al [ CMPL_2014]. The crust has been reconstructed in a thermodynamically consistent and unified way using the CUTER tool [DDFG_2025,DDFG_2024], see [DDFG_2025] for details.
