Crust glass formation reveals the neutron star birth properties in IGR J17480-2446
D. A. Baiko, A. I. Chugunov
IGR J17480-2446 is a low-mass X-ray binary, harboring an exceptional accreting pulsar (a neutron star) with an unusual spin frequency of 11 Hz and a very slow post-outburst crust c…
Constraining shear modulus of polycrystalline neutron star crust: Hashin-Shtrikman variational approach
Nikita A. Zemlyakov, Andrey I. Chugunov
The elastic properties of the neutron star crust are thought to play a crucial role in various phenomena of neutron stars (glitches, oscillations, gravitational wave emission) and…
Filling fractions for the formation of nuclear pasta in neutron stars: semiclassical vs liquid-drop predictions
Nikolai N. Shchechilin, Nicolas Chamel, Andrey I. Chugunov
Historically, a sequence of nuclear pasta shapes was predicted to appear in the deepest region of the inner crust of a neutron star within the compressible liquid-drop picture, whe…
Pressure and chemical potentials in the inner crust of a cold neutron star within Hartree-Fock and extended Thomas-Fermi methods
Nicolas Chamel, Nikolai N. Shchechilin, Andrey I. Chugunov
Self-consistent mean-field methods with Skyrme-type effective interactions and semiclassical approximations, such as the Thomas-Fermi approach and its extensions are particularly w…
Cooling of neutron stars in soft X-ray transients with realistic crust composition
A. Y. Potekhin, A. I. Chugunov, N. N. Shchechilin +1
Thermal radiation of neutron stars in soft X-ray transients (SXTs) in a quiescent state is believed to be powered by the heat deposited in the stellar crust due to nuclear reaction…
On variational trial functions in the extended Thomas-Fermi method
A. Y. Potekhin, A. I. Chugunov, N. N. Shchechilin +1
Parametrized nucleon density distributions are widely employed for the calculation of the properties of atomic nuclei and dense inhomogeneous matter in compact stars within the Tho…
