The Exponential is Unique: Only G_eff = G·exp(−ρ/ρ_c) is Compatible with Neutron Star Observations
Abstract
First numerical verification of the maximum neutron star mass predicted by the CCEGA framework. TOV equations with G_eff(ρ) = G_N·exp(−ρ/ρ_c) and APR4 EOS yield M_max = 2.330 M☉ and R(1.4 M☉) = 12.63 km, consistent with PSR J0952-0607 and NICER. The exponential functional form is uniquely selected among power-law alternatives. ρ_c = 7.4 ρ_nuc derived independently from QCD transition physics (P18) — not fitted to stellar data.
