Neutron transfer reactions in accreting neutron stars [PDF]

open access: yesMNRAS:Letters 483, L47-L51 (2019), 2018
I suggest a novel type of nuclear reactions in accreting neutron stars - neutron transfer, which is quantum tunneling of weakly bounded neutron from one nucleus to another. I estimate the rate of this process for fixed nuclei separation and then average the result over realistic distribution of nuclei to get the rate value for astrophysical conditions.

Insights on Skyrme parameters from GW170817

open access: yesPhysics Letters B, 2019
The binary neutron-star merger event, GW170817, has cast a new light on nuclear physics research. Using a neutron-star model that includes a crust equation of state (EoS), we calculate the properties of a 1.4 solar-mass neutron star.

Monster Radiative Shocks in the Perturbed Magnetospheres of Neutron Stars

open access: yesThe Astrophysical Journal, 2023
Magnetospheres of neutron stars can be perturbed by star quakes, interaction in a binary system, or sudden collapse of the star. The perturbations are typically in the kilohertz band and excite magnetohydrodynamic waves.

High Velocity Neutron Stars as a Result of Asymmetric Neutrino Emission

open access: yes, 1997
Formation of a neutron star is accompanied by neutrino emission carring about 10% of the rest energy of the star. Toroidal field produced by twisting of a dipole field in differentially rotating star is antisymmetric.

A Chandra observation of the long-duration X-ray transient KS 1731-260 in quiescence: too cold a neutron star? [PDF]

open access: yes, 2001
After more than a decade of actively accreting at about a tenth of the Eddington critical mass accretion rate, the neutron-star X-ray transient KS 1731-260 returned to quiescence in early 2001. We present a Chandra/ACIS-S observation taken several months

Superfluid neutron stars [PDF]

open access: yes, 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 ...

Spin-polarized neutron matter, the maximum mass of neutron stars, and GW170817 [PDF]

open access: yesAstrophys. J. 892, 14 (2020), 2019
We investigate how a phase transition from neutron-star matter to spin-polarized neutron matter affects the equation of state and mass-radius relation of neutron stars. While general extension schemes for the equation of state allow for high pressures inside neutron stars, we find that a phase transition to spin-polarized neutron matter excludes ...

Probing neutron star physics using accreting neutron stars

open access: yesEPJ Web of Conferences, 2010
We give an obervational overview of the accreting neutron stars systems as probes of neutron star physics. In particular we focus on the results obtained from the periodic timing of accreting millisecond X-ray pulsars in outburst and from the ...

Intermediate-Mass-Elements in Young Supernova Remnants Reveal Neutron Star Kicks by Asymmetric Explosions

open access: yes, 2018
The birth properties of neutron stars yield important information on the still debated physical processes that trigger the explosion and on intrinsic neutron-star physics.

Low Mass Neutron Stars and the Equation of State of Dense Matter [PDF]

open access: yes, 2002
Neutron-star radii provide useful information on the equation of state of neutron rich matter. Particularly interesting is the density dependence of the equation of state (EOS).
