Time Evolution of Relativistic Force-Free Fields Connecting a Neutron Star and its Disk
, 2005 We study the magnetic interaction between a neutron star and its disk by solving the time-dependent relativistic force-free equations. At the initial state, we assume that the dipole magnetic field of the neutron star connects the neutron star and its ...

Universality and properties of neutron star type I critical collapses
, 2011 We study the neutron star axisymmetric critical solution previously found in the numerical studies of neutron star mergers. Using neutron star-like initial data and performing similar merger simulations, we demonstrate that the solution is indeed a semi ...

The extended, relativistic hyperon star model [PDF]
, 2002 In this paper an equation of state of neutron star matter which includes strange baryons in the framework of Zimanyi and Moszkowski (ZM) model has been obtained.

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.

Electromagnetic extraction of energy from black hole-neutron star binaries
, 2011 The coalescence of black hole-neutron star binaries is expected to be a principal source of gravitational waves for the next generation of detectors, Advanced LIGO and Advanced Virgo.

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 ...

The ultimate outcome of black hole - neutron star mergers
, 2004 We present a simple, semi--analytical description for the final stages of mergers of black hole (BH) -- neutron star (NS) systems. Such systems are of much interest as gravitational wave sources and gamma--ray burst progenitors.

Excitation of the odd-parity quasi-normal modes of compact objects [PDF]
, 1999 The gravitational radiation generated by a particle in a close unbounded orbit around a neutron star is computed as a means to study the importance of the $w$ modes of the neutron star.

Bound Debris Expulsion from Neutron Star Merger Remnants
The Astrophysical Journal, 2023 Many studies have found that neutron star mergers leave a fraction of the stars’ mass in bound orbits surrounding the resulting massive neutron star or black hole. This mass is a site of r -process nucleosynthesis and can generate a wind that contributes

Accretion dynamics in neutron star black hole binaries
, 2004 We perform three-dimensional, Newtonian hydrodynamic simulations with a nuclear equation of state to investigate the accretion dynamics in neutron star black hole systems.
