Entrainment in Superfluid Neutron Star Crusts: Hydrodynamic Description and Microscopic Origin
N. Chamel
In spite of the absence of viscous drag, the neutron superfluid permeating the inner crust of a neutron star cannot flow freely, and is entrained by the nuclear lattice similarly t…
Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. IX: Constraint of pairing force to neutron-matter gap
N. Chamel, S. Goriely, J. M. Pearson
In this latest of our series of Skyrme-HFB mass models, HFB-16, we introduce the new feature of requiring that the contact pairing force reproduce at each density the pairi…
Neutron drip transition in accreting and nonaccreting neutron star crusts
N. Chamel, A. F. Fantina, J. L. Zdunik +1
The neutron-drip transition in the dense matter constituting the interior of neutron stars generally refers to the appearance of unbound neutrons as the matter density reaches some…
Stability of super-Chandrasekhar magnetic white dwarfs
N. Chamel, A. F. Fantina, P. J. Davis
It has been recently proposed that very massive white dwarfs endowed with strongly quantizing magnetic fields might be the progenitors of overluminous type Ia supernovae like SN 20…
The Skyrme-Hartree-Fock-Bogoliubov method: its application to finite nuclei and neutron-star crusts
N. Chamel, S. Goriely, J. M. Pearson
After a brief review of the Hartree-Fock-Bogoliubov method with Skyrme effective interactions, we show how it can be applied to the description of various nuclear systems, from fin…
Superfluidity in Disordered Neutron Stars Crusts
J. A. Sauls, N. Chamel, M. A. Alpar
Nonequilibrium conditions imposed by neutrino cooling through the liquid-solid transition lead to disorder in the solid crust of neutron stars. Disorder reduces the superfluid frac…
