Effective-one-body model for coalescing binary neutron stars: Incorporating tidal spin and enhanced radiation from dynamical tides

In the late inspiral phase of compact binary coalescences involving neutron stars, tidal effects become increasingly important. Hang Yu and Shu Yan Lau model this system taking into consideration the tidal spin, the part of the spin that evolves in time due to tidal torquing, and its back reaction on the inspiral orbit. The rich picture developed could account for discrepancies between earlier models and numerical relativistic studies of these systems.
