Description

The analysis of Quasi Periodic Oscillations (QPOs) in Magnetars provided the first application of Asteroseismology in neutron stars. These oscillations are likely identified with magneto-elastic waves which originate in the giant flares. Cooling calculations show that magnetars become superfluid/superconducting systems in few hundred years from their birth. In this talk I will present the first dynamical study of superfluid magnetar models which incorporate the physics of superconducting protons and show its implications for the QPO Asteroseismology.
