Abstract

We study the role of time dependent magnetic ellipticities (epsilon(B)) on the calculation of the braking index of pulsars. Moreover, we study the consequences of such a epsilon(B) on the amplitude of gravitational waves (GWs) generated by pulsars with measured braking indices. We show that, since the ellipticity generated by the magnetic dipole is extremely small, the corresponding amplitude of GWs is much smaller than the amplitude obtained via the spindown limit. (AU)
