Gravitomagnetic resonant excitation of Rossby modes in coalescing neutron star binaries
Gravitomagnetic resonant excitation of Rossby modes in coalescing neutron star binaries
In coalescing neutron star binaries, $r$-modes in one of the stars can be resonantly excited by the gravitomagnetic tidal field of its companion. This post-Newtonian gravitomagnetic driving of these modes dominates over the Newtonian tidal driving previously computed by Ho and Lai. To leading order in the tidal expansion parameter …
