Fixing the center-of-mass frame of numerical relativity waveforms using the post-Newtonian center-of-mass charge
Aniket Khairnar, Leo C. Stein, Michael Boyle +7
The Bondi--van der Burg--Metzner--Sachs (BMS) frame of gravitational waves produced by numerical relativity (NR) simulations is crucial for building accurate waveform models. A pro…

Approximate helical symmetry in compact binaries
Aniket Khairnar, Leo C. Stein, Michael Boyle
The inspiral of a circular, non-precessing binary exhibits an approximate helical symmetry. The effects of eccentricity, precession, and radiation reaction break the exact symmetry…
