Magnetothermal evolution of neutron star cores in the `weak-coupling' regime: implications of ambipolar diffusion for the quiescent X-ray luminosity of magnetars
N. A. Moraga, F. Castillo, D. D. Ofengeim +5
The high quiescent X-ray luminosity observed in some magnetars is widely attributed to the decay and evolution of their ultra-strong magnetic fields. Several dissipation mechanisms…
Validating and improving two-fluid simulations of the magnetic field evolution in neutron star cores
F. Castillo, N. A. Moraga, M. E. Gusakov +2
This paper addresses the evolution of an axially symmetric magnetic field in the core of a neutron star. The matter in the core is modeled as a system of two fluids, namely neutron…
Two-fluid simulations of the magnetic field evolution in neutron star cores in the weak-coupling regime
F. Castillo, A. Reisenegger, J. A. Valdivia
In a previous paper, we reported simulations of the evolution of the magnetic field in neutron star cores through ambipolar diffusion, taking the neutrons as a motionless uniform b…
Magnetic field evolution and equilibrium configurations in neutron star cores: the effect of ambipolar diffusion
F. Castillo, A. Reisenegger, J. A. Valdivia
As another step towards understanding the long-term evolution of the magnetic field in neutron stars, we provide the first simulations of ambipolar diffusion in a spherical star. R…
