Microlensing neutron stars [PDF]
Astronomy & Astrophysics, 2002 We investigate the chances that neutron stars act as the lense in a gravitational microlensing event towards the galactic bulge or a spiral arm. The observation of neutron stars by means of gravitational microlensing would allow the estimation of neutron star masses independently of the property of being a pulsar in a binary system.

Universe, 2021 I review the issues related to the appearance of hyperons in neutron star matter, focusing in particular on the problem of the maximum mass supported by hyperonic equations of state. I discuss the general mechanism that leads to the formation of hyperons

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes
The Astrophysical Journal Letters, 2023 Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

Experimental Challenge to Heavy Element Synthesis under Explosive Burning on Neutron Stars [PDF]
EPJ Web of Conferences, 2020 Binary stellar systems that involve a neutron star or two neutron stars make interesting phenomena, X-ray bursts and kilo-novae, respectively, which involve explosive burning either in the proton-rich environment or in the neutron-rich environment. These

Holographic neutron stars [PDF]
Journal of High Energy Physics, 2010 We construct in the context of the AdS/CFT correspondence degenerate composite operators in the conformal field theory that are holographically dual to degenerate stars in anti de Sitter space. We calculate the effect of the gravitational back-reaction using the Tolman-Oppenheimer-Volkoff equations, and determine the "Chandrasekhar limit" beyond which ...

Thermodynamics of Hot Neutron Stars and Universal Relations
Universe, 2022 Over the last few years, the detection of gravitational waves from binary neutron star systems has rekindled our hopes for a deeper understanding of the unknown nature of ultradense matter.

Inferring the dense nuclear matter equation of state with neutron star tides [PDF]
EPJ Web of Conferences, 2022 During the late stages of a neutron star binary inspiral finite-size effects come into play, with the tidal deformability of the supranuclear density matter leaving an imprint on the gravitational-wave signal.

Semi-empirical relation to understand matter properties at neutron star interiors
European Physical Journal C: Particles and Fields, 2022 The occurrence of quark matter at the center of neutron stars is still in debate. This study defines some semi-empirical parameters that try to quantify the presence and the amount of quark matter at star interiors.

Hyperon-Mixed Neutron Star Matter and Neutron Stars [PDF]
Progress of Theoretical Physics, 2002 Effective Σ − n and Σ − Σ − interactions are derived fromthe G-matrix calculations for {n+Σ − } matter and employed in the investigation of hyperon mixing in neutron star matter. The threshold densities ρt(Y ) at which hyperons start to appear are between 2ρ0 and 3ρ0 (where ρ0 is the normal nuclear density) for both Λ and Σ − , and their fractions ...
