Gravitomagnetic corrections on gravitational waves
  Gravitational waveforms and production could be considerably affected by
gravitomagnetic corrections considered in relativistic theory of orbits. Beside
the standard periastron effect of General Relativity, new nutation effects come
out when c^{-3} corrections are taken into account. Such corrections emerge as
soon as matter-current densities and vector gravitational potentials cannot be
discarded into dynamics. We study the gravitational waves emitted through the
capture, in the gravitational field of massive binary systems (e.g. a very
massive black hole on which a stellar object is inspiralling) via the
quadrupole approximation, considering precession and nutation effects. We
present a numerical study to obtain the gravitational wave luminosity, the
total energy output and the gravitational radiation amplitude. From a crude
estimate of the expected number of events towards peculiar targets (e.g.
globular clusters) and in particular, the rate of events per year for dense
stellar clusters at the Galactic Center (SgrA*), we conclude that this type of
capture could give signatures to be revealed by interferometric GW antennas, in
particular by the forthcoming laser interferometer space antenna LISA.
