Gapless superfluidity in neutron stars: Thermal properties

Autor: Allard, Valentin, Chamel, Nicolas

Publikováno v: Phys. Rev. C 108, 015801 (2023)

The interior of mature neutron stars is expected to contain superfluid neutrons and superconducting protons. The influence of temperature and currents on superfluid properties is studied within the self-consistent time-dependent nuclear energy-densit

Report

Gapless neutron superfluidity can explain the late time cooling of transiently accreting neutron stars

Autor: Allard, Valentin, Chamel, Nicolas

The current interpretation of the observed late time cooling of transiently accreting neutron stars in low-mass X-ray binaries during quiescence requires the suppression of neutron superfluidity in their crust at variance with recent ab initio many-b

$^1$S$_0$ pairing gaps, chemical potential and entrainment matrix in superfluid neutron-star cores for the Brussels-Montreal functionals

Autor: Allard, Valentin, Chamel, Nicolas

Publikováno v: Universe 2021, 7(12), 470

Temperature and velocity-dependent $^1$S$_0$ pairing gaps, chemical potentials and entrainment matrix in dense homogeneous neutron-proton superfluid mixtures constituting the outer core of neutron stars, are determined fully self-consistently by solv

Publikováno v: Phys. Rev. C 100, 065801 (2019)

Mutual entrainment effects in cold neutron-proton mixtures are studied in the framework of the self-consistent nuclear energy-density functional theory. Exact expressions for the mass currents, valid for both homogeneous and inhomogeneous systems, ar

Entrainment effects in neutron-proton mixtures within the nuclear-energy density functional theory. II. Finite temperatures and arbitrary currents

Autor: Allard, Valentin, Chamel, Nicolas

Publikováno v: Phys. Rev. C 103, 025804 (2021)

Mutual entrainment effects in hot neutron-proton superfluid mixtures are studied in the framework of the self-consistent nuclear energy-density functional theory. The local mass currents in homogeneous or inhomogeneous nuclear systems, which we deriv
