General-relativistic resistive-magnetohydrodynamics simulations of self-consistent magnetized rotating neutron stars
read the original abstract
We present the first general-relativistic resistive magnetohydrodynamics simulations of self-consistent, rotating neutron stars with mixed poloidal and toroidal magnetic fields. Specifically, we investigate the role of resistivity in the dynamical evolution of neutron stars over a period of up to 100 ms and its effects on their quasi-equilibrium configurations. Our results demonstrate that resistivity can significantly influence the development of magnetohydrodynamic instabilities, resulting in markedly different magnetic field geometries. Additionally, resistivity suppresses the growth of these instabilities, leading to a reduction in the amplitude of emitted gravitational waves. Despite the variations in magnetic field geometries, the ratio of poloidal to toroidal field energies remains consistently 9:1 throughout the simulations, for the models we investigated.

Dense Matter and Compact Stars in Strong Magnetic Fields
Strong magnetic fields in compact stars induce Landau quantization and magnetic-moment couplings that change the equation of state and allow additional degrees of freedom such as hyperons, Delta resonances, and quark matter.

Non-magnetized evolution In this subsection, we compare the evolutions of a non- magnetized rapidly rotating neutron star with Gmunu and IllinoisGRMHD codes. The model employed in the case corresponds to a neutron stars with a central rest-mass density ρ = 4 .90 × 1014 g · cm−3, a gravitational mass M0 = 1.83M⊙, a radius RNS = 19.75 km along the x co- ord...

Magnetized evolution In this subsection, we compare the evolutions of the same strongly magnetized rapidly rotating neutron star model “A2” with Gmunu and IllinoisGRMHD codes. This neutron star is the “A2” model as described in section II and [34]. Note that, the finest grid size at the centre of the star in the case of Gmunu is ∆x ≈ 346 m, while it is ab...
