Description

Neutron stars exhibits the strongest magnetic field known while also being the most compact horizonless objects in the Universe, they are potential sources of coincident gravitational waves and electromagnetic radiation across the entire spectrum. However, the internal configuration of their magnetic field and the mechanism that stabilize them remain open questions. In this talk, via three-dimensional general relativistic magnetohydrodynamics simulations, we study the role of the magnetic field crust in the magnetic field evolution on isolated neutron stars. We find that, the addition of the crust stabilizes some magnetic field configurations, such as purely poloidal magnetic fields, which where believed to not be a stable configuration for the neutron star interior, while also finding mixed poloidal-toroidal stable configurations.
