Abstract	A rapidly rotating neutron star (NS) would emit gravitational waves (GWs) detectable by the GW detectors such as KAGRA, LIGO, VIRGO and the Einstein Telescope. The gravitational wave emitted from such an object suffers from Coulomb phase shift due to the gravitational potential of the emitter. The resulting phase shift depends on the mass of the emitter. We study the possibility of determining mass of an isolated rapidly rotating NS from a continuous GW signal emitted by the NS using the Einstein Telescope. We show that the NS mass can, in principle, be obtained by making use of the phase shift difference between two modes of the continuous GW such as once and twice the spin frequency induced by a freely precessing NS or a NS containing a pinned superfluid core. We estimate the measurement accuracy of the NS mass using Monte Carlo simulations.
