On the universality of I-Love-Q relations in magnetized neutron stars
Brynmor Haskell, Riccardo Ciolfi, Francesco Pannarale +1
Recently, general relations among the quadrupole moment (Q), the moment of inertia (I), and the tidal deformability (Love number) of a neutron star were shown to exist. They are ne…
Twisted-torus configurations with large toroidal magnetic fields in relativistic stars
Riccardo Ciolfi, Luciano Rezzolla
Understanding the properties of the internal magnetic field of neutron stars remains a theoretical challenge. Over the last years, twisted-torus geometries have been considered bot…
Poloidal-Field Instability in Magnetized Relativistic Stars
Riccardo Ciolfi, Luciano Rezzolla
We investigate the instability of purely poloidal magnetic fields in nonrotating neutron stars by means of three-dimensional general-relativistic magnetohydrodynamics simulations,…
Structure, Deformations and Gravitational Wave Emission of Magnetars
L. Gualtieri, R. Ciolfi, V. Ferrari
Neutron stars can have, in some phases of their life, extremely strong magnetic fields, up to 10^15-10^16 G. These objects, named magnetars, could be powerful sources of gravitatio…
Structure and deformations of strongly magnetized neutron stars with twisted torus configurations
R. Ciolfi, V. Ferrari, L. Gualtieri
We construct general relativistic models of stationary, strongly magnetized neutron stars. The magnetic field configuration, obtained by solving the relativistic Grad-Shafranov equ…
Relativistic models of magnetars: the twisted-torus magnetic field configuration
R. Ciolfi, V. Ferrari, L. Gualtieri +1
We find general relativistic solutions of equilibrium magnetic field configurations in magnetars, extending previous results of Colaiuda et al. (2008). Our method is based on the s…
