  Discovery of gravitational waves by LIGO team (Abbott et al. 2016) bring a
new era for observation of black hole systems. These new observations will
improve our knowledge on black holes and gravitational physics. In this study,
we present angular momentum loss mechanism through gravitational radiation for
selected X-ray binary systems. The angular momentum loss in X-ray binary
systems with a black hole companion due to gravitational radiation and mass
loss time-scales are estimated for each selected system. In addition, their
gravitational wave amplitudes are also estimated and their detectability with
gravitational wave detectors has been discussed.
