  General Relativity predicts that binary systems of stars produce
gravitational waves of significant intensity. Here we are particularly
interested in the cataclysmic variable binaries (CVs). These systems emit low
frequency gravitational waves, $ f < 10^{-3} Hz$. We present here a catalog of
CVs and argue that part of them are capable of being detected by the Laser
Interferometer Space Antenna (LISA).
