Effects of the phi Meson on the Properties of Hyperon Stars in the Density-dependent Relativistic Mean Field Model

Zhong-Hao Tu et al.

Summary: The effects of the phi meson on hyperon stars are systematically studied in a density-dependent relativistic mean field model. It is found that the phi meson can shift the hyperon threshold and affect the equation of state and maximum mass of hyperon stars. Only a few effective interactions survive under the constraints from astrophysical observations. The possibility of the secondary object of GW190814 being a rapidly rotating hyperon star is discussed.

PSR J0952-0607: The Fastest and Heaviest Known Galactic Neutron Star

Roger W. Romani et al.

Summary: We describe the Keck-telescope spectrophotometry and imaging of the companion of the black widow pulsar PSR J0952-0607. Despite the challenges posed by its faintness at minimum brightness, we were able to measure multicolor light curves and obtain radial velocities over half of the orbit. Our model fits indicate the system inclination and the mass of the pulsar, which is the largest well-measured mass found to date. This study is important for understanding the mass evolution of neutron stars.

Hadron-quark Pasta Phase in Massive Neutron Stars

Min Ju et al.

Summary: By extending the energy minimization (EM) method, we studied the possible appearance of hadron-quark pasta phases inside neutron stars, achieving local beta equilibrium within the Wigner-Seitz cell. The mixed phase described in the EM method helps in understanding the transition from the Gibbs construction to the Maxwell construction as surface tension increases.

Information Content of the Parity-Violating Asymmetry in 208P

Paul-Gerhard Reinhard et al.

Summary: The study focused on the parity-violating asymmetry A(PV) in Pb-208 using modern relativistic and nonrelativistic energy density functionals. By optimizing new functionals, predictions were made for the neutron skin thickness and symmetry-energy slope in Pb-208. The results were consistent with astrophysical data and differed from those obtained using a specific set of relativistic functionals.

Hyperons in Finite and Infinite Nuclear Systems

Isaac Vidana

Summary: This work briefly reviews the role and properties of hyperons in finite and infinite nuclear systems, including hypernuclei and neutron stars. It discusses different production mechanisms of hypernuclei, aspects of their gamma-ray spectroscopy and weak decay modes, as well as the theoretical description of hyperons. The paper also reexamines the impact of hyperons on neutron and proto-neutron star properties, focusing on the hyperon puzzle and proposed solutions. Finally, it reviews the role of hyperons in the cooling properties of newly born neutron stars and the r-mode instability.

GW190814: on the properties of the secondary component of the binary

Bhaskar Biswas et al.

Summary: The secondary object in GW190814 could be either a neutron star or a black hole, depending on its mass and spin. By using a Bayesian framework with a hybrid equation of state formulation, the properties of the secondary object can be deduced, along with the potential implications on equation of state and compact object formation channels.

Was GW190814 a Black Hole-Strange Quark Star System?

I Bombaci et al.

Summary: The possibility of the low mass companion of the black hole in the source of GW190814 being a strange quark star has been investigated. It is viable within the two-families scenario where neutron stars and strange quark stars coexist. Strange quark stars and neutron stars fulfill different astrophysical and nuclear physics constraints.

Impact of the PSR J0740+6620 radius constraint on the properties of high-density matter

Isaac Legred et al.

Summary: The X-ray pulse profile modeling of PSR J0740+6620 using data from NICER and XMM-Newton observatories has led to a measurement of its radius, providing insight into the neutron star equation of state (EoS). The analysis mildly disfavors EoSs supporting a disconnected hybrid star branch and reveals core matter with strong interactions violating the conformal sound-speed bound. Results suggest a relatively stiff EoS and limit the density range probed by observations of cold, non-rotating neutron stars in beta-equilibrium.

Maximum mass of compact stars from gravitational wave events with finite-temperature equations of state

Sanika Khadkikar et al.

Summary: Researchers have proposed and verified a set of relations regarding the global parameters of hot and fast-rotating compact stars, independent of the equation of state, including a relation between mass-shedding and static configurations. By applying these relations to the GW170817 event, an upper limit on the maximum mass of cold, static neutron stars was deduced, suggesting that considering the temperature of merger remnants can relax previously derived constraints on the maximum mass of cold, static compact stars.

Supermassive neutron stars rule out twin stars

Jan-Erik Christian et al.

Summary: In this study, the implications of a hypothetical 2.5 solar mass neutron star for a first-order phase transition to quark matter were investigated. A strong connection between the discontinuity in energy density and the maximal neutron star mass was found, demonstrating that high maximal masses cannot be realized for large discontinuities. This study also showed that visible mass gaps and masses greater than or similar to 2.2 solar masses are mutually exclusive.

GW190814 as a massive rapidly rotating neutron star with exotic degrees of freedom

V Dexheimer et al.

Summary: This study investigates the possibility of producing massive neutron stars from different equation of state models, showing that quark interactions and nonstandard self-vector interactions can generate massive stars. The research also reveals that fast rotation may not necessarily suppress exotic degrees of freedom, and stars with pure quark cores can easily reach 2.5 solar masses.

Summary: The study focuses on rapidly spinning compact stars with a first-order phase transition between strongly coupled nuclear matter and deconfined quark matter. Models allow for purely hadronic uniformly rotating stars with masses up to approximately 2.9 solar masses, and the maximal mass is determined by the phase transition in cases with the largest values.

On the Nature of GW190814 and Its Impact on the Understanding of Supranuclear Matter

Ingo Tews et al.

Summary: The observation suggests that the compact object has a mass of 2.50-2.67M99.9%, and even with relaxed constraints on the maximum mass of neutron stars, the probability of a binary black hole origin remains around 81%. Analysis of the allowed region in the mass-radius diagram for neutron stars indicates that the scenario with a neutron star as the secondary object would require a rather stiff equation of state.
