The first calculation of the frequency spectrum of gravitational wave mass quadrupole radiation for binaries on hyperbolic orbits was performed in arXiv:1207.5359. Some shortcomings of their derivation were pointed out, but there are still inaccuracies and supplements that we believe are worthwhile to communicate. In this note we provide a consistent and straightforward exposition of the frequency spectrum in the case of hyperbolic encounters and explicitly determine the parabolic limit, which was not possible with the previous treatments.

  1. Parameter estimation of gravitational waves from hyperbolic black hole encounters

    gr-qc 2025-07 conditional novelty 6.0 of 10

    RIFT can recover the masses, spins, and orbital energy and angular momentum of simulated hyperbolic black hole encounters when paired with the TEOBResumSDALI waveform model.

  2. Scalar kicks and memory

    gr-qc 2024-12 conditional novelty 6.0 of 10

    For hyperbolic binaries, a conformally coupled scalar changes the memory and zero-frequency power while a disformally coupled scalar changes only the center-of-mass kick.
