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…
