abstract = "We study a binary system composed of point particles of unequal
masses in eccentric orbits in the linear regime of the
characteristic formulation of general relativity, generalising a
previous study found in the literature in which a system of equal
masses in circular orbits is considered. We also show that the
boundary conditions on the time-like world tubes generated by the
orbits of the particles can be extended beyond circular orbits.
Concerning the power lost by the emission of gravitational waves,
it is directly obtained from the Bondi's News function. It is
worth stressing that our results are completely consistent,
because we obtain the same result for the power derived by Peters
and Mathews, in a different approach, in their seminal paper of
1963. In addition, the present study constitutes a powerful tool
to construct extraction schemes in the characteristic formalism to
obtain the gravitational radiation produced by binary systems
during the inspiralling phase.",
