Relativistic Brueckner-Hartree-Fock Calculations for Cold and Hot Neutron Stars.

FARRELL D. and WEBER F.

Abstract (from CDS):

This study investigates the properties of symmetric and asymmetric nuclear matter using the relativistic Brueckner-Hartree-Fock formalism, examining both zero and finite temperatures up to 70 MeV. Employing the full Dirac space, we incorporate three Bonn potentials (A, B, and C), which account for meson masses, coupling strengths, cutoff parameters, and form factors. The calculated properties of asymmetric nuclear matter form the basis for constructing equation-of-state (EOS) models tailored for neutron stars. These models, in turn, enable the computation of bulk properties for nonrotating, uniformly rotating, and differentially rotating neutron stars. Notably, the EOS models studied in this paper are sufficiently versatile to accommodate the mass of the most massive neutron star ever detected, PSR J0952-0607, estimated to be 2.35 ± 0.17 M⊙. Furthermore, they yield masses and radii for PSR J0030+451 that align with the confidence intervals established for this pulsar.
