Eccentric Point Particle Binaries In The Linear Regime Of The Characteristic Formulation Of General Relativity 
Abstract 
A study of binary systems composed of two point particles in eccentric orbits in the linear regime of the characteristic formulation of general relativity is provided. The boundary conditions at the world tubes generated by the particle's orbits are explored, when the metric variables are decomposed in spinweighted spherical harmonics. The power lost by the emission of gravitational waves is computed using the News Bondi's function, and the contribution to the gravitational radiation of several multipole terms is shown.
