Beyond the Tayler instability: A new global instability of toroidal magnetic fields in stars
Mikhail E. Gusakov, Laura Becerra, Elena M. Kantor +2
Stellar toroidal magnetic fields are known to be unstable to the Tayler instability. Here we demonstrate the existence of a complementary current-driven instability of essentially…
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…
Stability of axially symmetric magnetic fields in stars
L. Becerra, A. Reisenegger, J. A. Valdivia +1
The magnetic fields observed in Ap-stars, white dwarfs, and neutron stars are known to be stable for long times. However, the physical conditions inside the stellar interiors that…
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…
