Measuring the masses and radii of neutron stars in low-mass X-ray binaries: Effects of the atmospheric composition and touchdown radius

Myungkuk Kim et al.

Summary: This study examines the impact of photospheric composition and touchdown radius on the estimation of neutron star mass and radius in X-ray bursts and PRE XRBs. It is found statistically that a H-poor photosphere and a large touchdown radius are favored, possibly due to the correlation between a more H-poor photosphere and a farther touchdown from the neutron star surface. The neutron star radii in these six LMXBs are likely less than 12.5 km considering uncertainties, consistent with constraints based on gravitational wave signals.

Accurate Determination of the Neutron Skin Thickness of 208Pb through Parity-Violation in Electron Scattering

D. Adhikari et al.

Summary: The study reports a precise measurement of the parity-violating asymmetry A(pv) in elastic scattering of longitudinally polarized electrons from Pb-208, extracting key parameters such as neutron skin thickness and interior baryon density. This measurement accurately constrains the density dependence of the symmetry energy of nuclear matter near saturation density, with implications for the size and composition of neutron stars.

Implications of PREX-2 on the Equation of State of Neutron-Rich Matter

Brendan T. Reed et al.

Summary: Laboratory experiments sensitive to the equation of state of neutron rich matter in the vicinity of nuclear saturation density provide crucial data connecting terrestrial experiments to astronomical observations. The neutron skin thickness of Pb-208 further constrains the density dependence of the symmetry energy. The impact of a stiff symmetry energy on critical neutron-star observables is studied.

Fluctuations and phases in baryonic matter

Len Brandes et al.

Summary: The study focuses on the role of fluctuations beyond the mean-field approximation in the phase structure of baryonic matter. It examines the chiral nucleon-meson model and its applications to nuclear matter, including the liquid-gas phase transition and high baryon densities. Vacuum fluctuations are found to stabilize the hadronic phase characterized by spontaneously broken chiral symmetry.

Progress in Constraining Nuclear Symmetry Energy Using Neutron Star Observables Since GW170817

Bao-An Li et al.

Summary: The density dependence of nuclear symmetry energy is one of the most uncertain parts of the Equation of State (EOS) of dense neutron-rich nuclear matter. New observational data of neutron stars since GW170817 have contributed to an improved understanding of nuclear symmetry energy, particularly at high densities.

Implications of PREX-2 on the electric dipole polarizability of neutron-rich nuclei

J. Piekarewicz

Summary: The study focuses on the constraints of symmetry energy through the neutron skin thickness of Pb-208 and electric dipole polarizability, finding significant discrepancies between theoretical predictions and experimental values. These experimental tools offer clues to constrain the symmetry energy around nuclear saturation density, but there remains a contradiction in the hardness of the symmetry energy.

Summary: The study explores the impact of nuclear symmetry energy parameters on nuclear and neutron star properties using the KIDS framework, determining a small regime of best-performing parameters where K-sym is negative, K-tau lies between -400 and -300 MeV, and L lies between 40 and 65 MeV.
