Magneto-elastic equilibrium of a neutron star crust

ABSTRACT We examine the equilibrium of a magnetized neutron star crust. calculate axially symmetric models in which an elastic force balances solenoidal motion driven by Lorentz force. A large variety are allowed incorporating shear deformation; addition, toroidal-magnetic-field-dominated available. These results remarkably differ from those barotropic fluid stars. demonstrate some wherein magnetic energy exceeds energy. The excess comes fact that amount is associated with irrotational part force, balanced gravity and pressure. It sufficient for minor weak find elasticity crust plays important role on field confinement. Further, we present spatial distribution stress at limit, crust-fracture location can be identified. result has useful implications realistic crust-quake models.
