  Tidal and tidal-resonant effects in coalescing compact binary systems are
investigated by direct numerical integration of the equations of motion. For
the stars polytropic models are used. The tidal effects are found to be
dominated by the (non-resonant) $f$-modes. The effect of the $g$-mode-tidal
resonances is obtained. The tidal interaction is shown to be of interest
especially for low-mass binaries. There exists a characteristic final plunge
orbit beyond which the system cannot remain stable even if radiation reaction
is not taken into account; in agreement with results obtained by Lai et al.
\shortcite{Lai93}. The importance of the investigated effects for the
observation of gravitational waves on Earth is discussed.
