Effects of tidal resonances to the evolution of compact star binaries, such as binary neutron stars or neutron star-black hole binaries, are studied. We apply the Press-Teukolsky algorithm to a simple neutron star model whose companion moves with a circular orbit. To see effects of the tidal resonances, we compare the deposited energy in the star with the dissipated energy of a circular motion due to the emission of gravitational waves. It is found that under realistic situations, the g-mode resonance oscillations do not affect the evolution of binary systems so much, while the f-mode may induce a transition from a steady inspiral to an unstable plunge of compact star binaries.
