                         provided. The present paper generalizes a previous study by Bishop 
                         et al. The boundary conditions at the world tubes generated by the 
                         particles's orbits are explored, where the metric variables are 
                         decomposed in spin-weighted spherical harmonics. The power lost by 
                         the emission of gravitational waves is computed using the Bondi 
                         News function. The power found is the well-known result obtained 
                         by Peters and Mathews using a different approach. This agreement 
                         validates the approach considered here. Several multipole term

                         shown.",
