Proto-Neutron Star Evolution Dataset: Comprehensive Equation of State and Mass-Radius Relations

This dataset contains comprehensive equation of state (EOS) and mass-radius data for neutron stars and proto-neutron stars, supporting the research presented in "Constraints on maximum neutron star mass from proto-neutron star evolution" (arXiv:2505.18888). The dataset comprises 18 compressed CSV files totaling ~6.4 GB, containing over 150 million data points from relativistic mean field calculations. The data covers both nucleonic and hyperonic matter under various thermodynamic conditions relevant to neutron star cores and proto-neutron star evolution. Key features:- Zero temperature and finite temperature equations of state- Beta-equilibrium conditions with trapped neutrinos- Mass-radius relations for neutron stars and proto-neutron stars- Particle composition data including hyperons- Comprehensive coverage from nuclear saturation to ~10 times nuclear density- Temperature range covering proto-neutron star evolution (0-50 MeV)
