P29 v1.4: Maximum Neutron Star Mass in CCEGA – Numerical Verification with Six Equations of State

Key Points

This research aims to verify the maximum neutron star mass using numerical methods across six equations of state.
Extended numerical verification using six standard equations of state (APR4, SLy, MPA1, ENG, H4, MS1)
Calculation of maximum neutron star mass (M_max) with CCEGA framework
Comparison of neutron star mass with observational data from PSR J0952-0607
Maximum neutron star mass (M_max) calculated at 4.26 ± 0.04 M☉
General relativity predicts a maximum range of 1.52–2.26 M☉
PSR J0952-0607 observed mass at 2.35 ± 0.17 M☉ aligns with CCEGA predictions, suggesting stress on general relativity

Abstract

Extended numerical verification with six standard equations of state (APR4, SLy, MPA1, ENG, H4, MS1). CCEGA: Mₘax = 4. 26 ± 0. 04 M☉. General Relativity: Mₘax = 1. 52–2. 26 M☉. PSR J0952-0607 (2. 35 ± 0. 17 M☉) places observational stress on GR while consistent with CCEGA (margin +1. 91 M☉). Comprehensive comparison and falsification thresholds.
