Third order post-Newtonian gravitational radiation from two-body scattering: Instantaneous energy and angular momentum radiation

Published in Phys.Rev.D 105 (2022) 8, 084018, 2021

We compute the third post-Newtonian (3PN) accurate instantaneous contributions to the radiated gravitational wave energy and angular momentum arising from the hyperbolic passages of nonspinning compact objects. The present computations employ 3PN-accurate instantaneous contributions to the far-zone energy and angular momentum fluxes and the 3PN-accurate Keplerian type parametric solution for compact binaries in hyperbolic orbits.
