Evolution of Neutron Stars and Observational Constraints
EPJ Web of Conferences, 2010 The structure and evolution of neutron stars is discussed with a view towards constraining the properties of high density matter through observations.

Radii of neutron drops probed via the neutron skin thickness of nuclei [PDF]
Phys. Rev. C 94, 041302 (2016), 2016 Multi-neutron systems are crucial to understanding the physics of neutron-rich nuclei and neutron stars. Neutron drops, neutrons confined in an external field, are investigated systematically in both non-relativistic and relativistic density functional theories and with ab initio calculations.

The cosmic merger rate of neutron stars and black holes [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Six gravitational wave detections have been reported so far, providing crucial insights on the merger rate of double compact objects. We investigate the cosmic merger rate of double neutron stars (DNSs), neutron star-black hole binaries (NSBHs) and black

Neutrostriction in Neutron Stars [PDF]
Old and New Concepts of Physics, 2007 It is demonstrated that not only gravity, but also neutrostriction forces due to optical potential created by coherent elastic neutron-neutron scattering can hold a neutron star together. The latter forces can be stronger than gravitational ones. The effect of these forces on mass, radius and structure of the neutron star is estimated.

Fallback supernova assembly of heavy binary neutron stars and light black hole-neutron star pairs and the common stellar ancestry of GW190425 and GW200115 [PDF]
, 2021 The detection of the unusually heavy binary neutron star merger GW190425 marked a stark contrast to the mass distribution from known Galactic pulsars in double neutron star binaries and gravitational-wave source GW170817. We suggest here a formation channel for heavy binary neutron stars and light black hole - neutron star binaries in which massive ...

On the minimum mass of neutron stars [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We investigate remnant neutron star masses (in particular, the minimum allowed mass) by performing advanced stellar evolution calculations and neutrino-radiation hydrodynamics simulations for core-collapse supernova explosions.

Dark halos around neutron stars and gravitational waves [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We find that models of MeV-GeV dark matter in which dark matter interacts strongly can be constrained by the observation of gravitational waves from binary neutron star (BNS) mergers.

Effects of dark matter on the spontaneous scalarization in neutron stars
European Physical Journal C: Particles and FieldsDark matter, an important portion of compact objects, can influence different phenomena in neutron stars. The spontaneous scalarization in the scalar-tensor gravity has been proposed for neutron stars.
