R-mode oscillations of rotating neutron stars(NS) are promising candidatesfor continuous gravitational wave (GW) observations. In our recent work, wederived universal relations of the NS parameters, compactness and dimensionlesstidal deformability with the r-mode frequency. In this work, we investigate howthese universal relations can be used to infer various NS intrinsic parametersfollowing a successful detection of the r-modes. In particular, we show thatfor targeted r-mode searches, these universal relations along with the"I-Love-Q" relation can be used to estimate both the moment of inertia and thedistance of the NS thus breaking the degeneracy of distance measurement forcontinuous gravitational wave(CGW) observations. We also discuss that with aprior knowledge of the distance of the NS from electromagnetic observations,these universal relations can also be used to constrain the dense matterequation of state (EOS) inside NS. We quantify the accuracy to which suchmeasurements can be done using the Fisher information matrix for a broad rangeof possible, unknown parameters, for both the a-LIGO and Einstein Telescope(ET) sensitivities.
