Physical Review Letters, 1964 Several authors have suggested that the recently discovered extraterrestrial sources of x rays may be hot neutron stars. The plausibility of this suggestion, and in fact the likelihood that astronomers will ever be able to observe neutron stars by their

Spontaneous scalarization in proto-neutron stars [PDF]
European Physical Journal C: Particles and Fields, 2023 Proto-neutron stars are born when a highly evolved and massive star collapses under gravity. In this paper, we investigate the spontaneous scalarization in proto-neutron stars.

QCD equations of state and speed of sound in neutron stars [PDF]
AAPPS Bulletin, 2021 Neutron stars are cosmic laboratories to study dense matter in quantum chromodynamics (QCD). The observable mass-radius relations of neutron stars are determined by QCD equations of state and can reflect the properties of QCD phase transitions.

Neutron-mirror neutron mixing and neutron stars [PDF]
European Physical Journal C: Particles and Fields, 2021 The oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter.

The mass distribution of Galactic double neutron stars [PDF]
Astrophysical Journal, 2019 The conventional wisdom, dating back to 2012, is that the mass distribution of Galactic double neutron stars is well-fit by a Gaussian distribution with a mean of $1.33 M_\odot$ and a width of $0.09 M_\odot$.

Hyperons in Neutron Stars [PDF]
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

Superfluid neutron stars [PDF]
The Ninth Marcel Grossmann Meeting, 2001 Neutron stars are believed to contain (neutron and proton) superfluids. I will give a summary of a macroscopic description of the interior of neutron stars, in a formulation which is general relativistic. I will also present recent results on the oscillations of neutron stars, with superfluidity explicitly taken into account, which leads in particular ...

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.

Studying strong phase transitions in neutron stars with gravitational waves [PDF]
Phys. Rev. D 101, 044019 (2020), 2019 The composition of neutron stars at the extreme densities reached in their cores is currently unknown. Besides nuclear matter of normal neutrons and protons, the cores of neutron stars might harbor exotic matter such as deconfined quarks. In this paper we study strong hadron-quark phase transitions in the context of gravitational wave observations of ...
