  "abstract": "In this paper we investigate the effect of a pinned superfluid component on the gravitational wave emission of a steadily rotating deformed neutron star. We show that the superfluid pinning allows the possibility for there to be gravitational wave emission at both the stellar spin frequency $\\Omega$ and its first harmonic, $2\\Omega$. This contrasts with the conventional case where there is no pinned superfluidity, where either only the $2\\Omega$ harmonic is present, or else the star undergoes precession, a feature which is not believed to be common in the known pulsar population. This work motivates the carrying out of gravitational wave searches where both the $\\Omega$ and $2\\Omega$ harmonics are searched for, even in targeted searches for waves from known pulsars which aren't observed to precess. Observation of such a two-component signal would provide evidence in favour of pinned superfluidity inside the star.",
