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…

Magneto-thermal evolution in the cores of adolescent neutron stars: The Grad-Shafranov equilibrium is never reached in the 'strong-coupling' regime
Nicolás A. Moraga, Francisco Castillo, Andreas Reisenegger +2
At the high temperatures present inside recently formed neutron stars (), the particles in their cores are in the "strong-coupling" regime, in w…
