    Abstract:

    We study torsional Alfvén oscillations of magnetars, i.e., neutron stars with a strong magnetic field. We consider the poloidal and toroidal components of the magnetic field and a wide range of equilibrium stellar models. Our results can explain both the lower and the higher observed frequencies in SGR 1806-20 and SGR 1900+14.
