Gravitational waveforms of binary neutron star inspirals using post-Newtonian tidal splicing

Understand

The tidal deformations of neutron stars within an inspiraling compact binary alter the orbital dynamics, imprinting a signature on the gravitational wave signal.

• Modeling this signal could be done with numerical-relativity simulations, but these are too computationally expensive for many applications.
• Analytic post-Newtonian treatments are limited by unknown higher-order nontidal terms.
• This paper further builds upon the "tidal splicing" model in which post-Newtonian tidal terms are "spliced" onto numerical relativity simulations of black-hole binaries.
