Timing of the Crab and Vela pulsars have recently revealed very peculiar evolutions of their spin frequency during the early stage of a glitch. We show that these differences can be interpreted from the interactions between neutron superfluid vortice

Our recent Newtonian treatment of the smooth-averaged mutual-friction force acting on the neutron superfluid and locally induced by the pinning of quantized neutron vortices to proton fluxoids in the outer core of superfluid neutron stars is here ada

The role of the crust on the tidal deformability of a cold nonaccreted neutron star is studied using the recent unified equation of state BSk24. This equation of state, which is based on the nuclear-energy density functional theory, provides a thermo

International audience; We describe recent progress in the modelling of realistic equilibrium configurations of rotating superfluid neutron stars, in a fully general relativistic framework. We compute stationary and axisymmetric configurations of neu

Realistic global neutron star models require numerical approach. Here, we briefly motivate and recall the general-relativistic framework for the description of rotating compact stars and show how global observable quantities can be computed unambiguo
