Long term resistive GRMHD simulations of self-consistent rotating neutron stars with mixed magnetic fields

Highly magnetized neutron stars are promising candidates for peculiar astronomical phenomena, including fast radio bursts, soft gamma-ray repeaters and X-ray pulsars.

Detailed investigation of the dynamics of these systems is extremely challenging yet significant.

Despite much amount effort has been made in magnetohydrodynamic in the context of neutron stars, their quasi-equilibrium configurations are still largely unknown.

In this talk, we present the first long term full 3D resistive GRMHD simulations of self-consistent rotating neutron stars with mixed poloidal and toroidal fields.

In particular, we will discuss the dynamical instabilities took place at the beginning of the simulation, and discuss the possible quasi-equilibrium configurations obtained from the end of the simulations.

Moreover, we will also discuss the role played by resistivity in the dynamical evolution of neutron stars, and hence their effects onto the neutron star quasi-equilibrium configurations.
