The moment of inertia of the neutron star PSR J0348+0432 and its proto neutron star [PDF]

open access: yes, 2017
The difference of the moment of inertia of the neutron star PSR J0348 + 0432 and that of its proto neutron star is studied in the framework of the relativistic mean field theory considering baryon octet. The temperature of the proto neutron star PSR J0348+0432 is chosen as T=5 MeV.

The influence of the enhanced vector meson sector on the properties of the matter of neutron stars. [PDF]

open access: yesPLoS ONE, 2014
This paper gives an overview of the model of a neutron star with non-zero strangeness constructed within the framework of the nonlinear realization of the chiral SU(3)L x SU(3)R symmetry.

Rapidly Rotating Neutron Stars in Dilatonic Einstein-Gauss-Bonnet Theory [PDF]

open access: yesPhys. Rev. D 93, 064077 (2016), 2016
We construct sequences of rapidly rotating neutron stars in dilatonic Einstein-Gauss-Bonnet theory, employing two equations of state for the nuclear matter. We analyze the dependence of the physical properties of these neutron stars on the Gauss-Bonnet coupling strength.

An Accretion Model for Anomalous X-Ray Pulsars

open access: yes, 1999
We present a model for the anomalous X-ray pulsars (AXPs) in which the emission is powered by accretion from a fossil disk, established from matter falling back onto the neutron star following its birth.

Neutron Stars and Dark Matter

open access: yesUniverse, 2020
Neutron stars change their structure with accumulation of dark matter. We study how their mass is influenced from the environment. Close to the sun, the dark matter accretion from the neutron star does not have any effect on it.

Neutron stars from crust to core within the Quark-meson coupling model [PDF]

open access: yesEPJ Web of Conferences, 2020
Recent years continue to be an exciting time for the neutron star physics, providing many new observations and insights to these natural ‘laboratories’ of cold dense matter.

On the state of low luminous accreting neutron stars

open access: yes, 2001
Observational appearance of a neutron star in the subsonic propeller state which is a companion of a wind-fed mass-exchange close binary system is discussed.

Anisotropic magnetized neutron star

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
As we know, the effect of strong magnetic field causes the anisotropy for the magnetized compact objects. Therefore, in this paper, we have studied the structure properties of anisotropic case of magnetized neutron star.
