New constraints on the neutron-star mass and radius relation from terrestrial nuclear experiments

Hajime Sotani et al.

Summary: The determination of the equation of state (EOS) for nuclear matter is crucial for understanding the properties of neutron stars. Recent nuclear experiments have been performed to constrain the density dependence of the nuclear symmetry energy. However, additional constraints from astronomical observations are needed due to the large uncertainties in these experiments. This study investigates the allowed area of the neutron-star mass and radius relation using constraints from specific experiments and finds consistency with astronomical observations, highlighting the importance of terrestrial nuclear experiments in providing further constraints on the EOS for neutron stars.

Gravitational wave asteroseismology on cooling neutron stars

Hajime Sotani et al.

Summary: This article examines the gravitational wave frequencies from neutron stars during thermal evolution and finds a strong correlation between the frequencies and the properties of the neutron star, such as mass and compactness. The article also derives an empirical formula to estimate the threshold mass for the onset of the direct Urca inside the neutron star.

Probing the Symmetry Energy with the Spectral Pion Ratio

J. Estee et al.

Summary: By measuring the ratio of charged pion spectra at high transverse momenta, we deduced the slope of the symmetry energy to be 42 < L < 117 MeV, which is slightly lower but consistent with the L values deduced from a recent measurement of the neutron skin thickness of Pb-208.

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.

Thomas E. Riley et al.

Summary: The study utilizes Bayesian estimation to analyze the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J0740+6620 based on Neutron Star Interior Composition Explorer X-ray Timing Instrument event data. The results show that the equatorial radius of PSR J0740+6620 is approximately 12.39 km, with a mass of about 2.072 solar masses, each reported within a specific posterior credible interval.
