High-energy emissions from neutron star mergers [PDF]
EPJ Web of Conferences, 2019 In 2017, LIGO-Virgo collaborations reported detection of the first neutron star merger event, GW170817, which is accompanied by electromagnetic counterparts from radio to gamma rays.

A novel solution to the hyperon-puzzle in neutron stars [PDF]
EPJ Web of ConferencesHyperons are baryons with strangeness content and heavier than nucleons. Due to the high densities in the neutron star interior, they are energetically allowed to appear.

The evolution of low mass, close binary systems with a neutron star component: a detailed grid [PDF]
, 2012 In close binary systems composed of a normal, donor star and an accreting neutron star, the amount of material received by the accreting component is, so far, a real intrigue.

Neutron Star Mergers and the Quark Matter Equation of State [PDF]
EPJ Web of Conferences, 2022 As neutron stars merge they can approach very high nuclear density. Here, we summarized recent results for the evolution and gravitational wave emission from binary-neutron star mergers using a a variety of nuclear equations of state with and without a ...

Bounds on Neutron- Mirror Neutron Mixing from Pulsar Timings and Gravitational Wave Detections [PDF]
Phys. Rev. D 100, 123021 (2019), 2019 The mass loss in putative neutron star to mixed neutron - mirror neutron star transition implies a significant change of orbital period. The precise constancy of the latter can restrict scenarios recently suggested where neutron to mirror neutron mixing occurring in neutron stars, transforms them into mixed stars helping explain the narrow mass ...

Physical Review Research, 2021 Gravitational waves from neutron star binary inspirals contain information on strongly interacting matter in unexplored, extreme regimes. Extracting this requires robust theoretical models of the signatures of matter in the gravitational-wave signals due

Bayesian Model Selection of Unified Neutron Star EOSs in Multi-messenger Era
Yuanzineng kexue jishu, 2023 The equation of state (EoS) of neutron star matter plays a key role in both the structure and evolution of a neutron star. However, as lattice QCD faces significant difficulties in simulating dense matter, only effective models can be relied on to unveil

On the minimum and maximum mass of neutron stars and the delayed collapse [PDF]
, 2000 The minimum and maximum mass of protoneutron stars and neutron stars are investigated. The hot dense matter is described by relativistic (including hyperons) and non-relativistic equations of state.

Nuclear Physics of the Outer Layers of Accreting Neutron Stars [PDF]
Journal of Physics G, 45, 093001 (2018, 2018 Now 50 years since the existence of the neutron star crust was proposed, we review the current understanding of the nuclear physics of the outer layers of accreting neutron stars. Nuclei produced during nuclear burning replace the nascent composition of the neutron star ocean and crust.

A magnetically driven origin for the low luminosity GRB 170817A associated with GW170817
, 2018 The gamma-ray burst GRB 170817A associated with GW170817 is subluminous and subenergetic compared with other typical short GRBs. It may be due to a relativistic jet viewed off-axis, or a structured jet, or cocoon emission. Giant flares from magnetars may
