Alfv\'en Polar Oscillations of Relativistic Stars (2009)
We study polar Alfv\'en oscillations of relativistic stars endowed with a strong global poloidal dipole magnetic field. Here we focus only on the axisymmetric oscillations which are studied by...

Constraints on the Magnetic Field Geometry of Magnetars (2007)
Sotani, H., Colaiuda, A., Kokkotas, K. D.
We study the effect of the magnetic field geometry on the oscillation spectra of strongly magnetized stars. The magnetic field distributions include both toroidal and poloidal contributions. We...

Sotani, H., Kokkotas, K. D., Stergioulas, N., Vavoulidis, M.
We investigate torsional Alfv\'{e}n modes of relativistic stars with a global dipole magnetic field. It has been noted recently (Glampedakis et al. 2006) that such oscillation modes could serve as as...

Sotani, H., Kokkotas, K. D., Stergioulas, N.
We present the formalism and numerical results for torsional oscillations of relativistic stars endowed with a strong dipole magnetic field. We do a systematic search of parameter space by computing...
