Description

We study here the r-modes in the Cowling approximation of a slowly rotating and magnetized neutron star with a poloidal magnetic field, where we neglect any deformations of the spherical symmetry of the star. We were able to quantify the influence of the magnetic field in both the oscillation frequency of the r-modes and the growth time of the gravitational radiation emission. We conclude that magnetic fields of the order 10^{15} G at the center of the star are necessary to produce any changes.
