Post Newtonian emission of gravitational waves from binary systems: a gauge theory perspective
arxiv(2023)
摘要
We derive a gauge inspired combinatorial formula based on localization for
the Post-Newtonian expansion of the gravitational wave form luminosity of
binary systems made of objects with very different masses orbiting at large
distances and small velocities. The results are tested against previous
formulae in the literature for Schwarschild and Kerr black holes at the 5th and
3rd Post Newtonian order respectively beyond the quadrupole approximation.
Tidal effects show up in the wave form at the 5th PN order, providing a
quantitative measure of the blackness/compactness properties of the heavy
object.
