Gravitational radiation from triple star systems

We have studied the main features of the gravitational radiation generated by an astrophysical system constituting of three compact objects attracting one another (only via gravitational interaction) in such a manner that sta ble orbits do exist. We have limited our analysis to systems that can be tr eated with perturbative methods. We show the profile of the gravitational w aves emitted by such systems. These results can be useful within the framew ork of the new gravitational astronomy which will be made feasible by means of the new generation of gravitational detectors such as LISA in a no long er far future.
