Dynamical tides during the inspiral of rapidly spinning neutron stars: Solutions beyond mode resonance
Hang Yu, Phil Arras, Nevin N. Weinberg
We investigate the dynamical tide in a gravitational wave (GW)-driven coalescing binary involving a neutron star (NS). The NS is assumed to spin rapidly, with its spin axis anti-al…
Beyond the linear tide: impact of the non-linear tidal response of neutron stars on gravitational waveforms from binary inspirals
Hang Yu, Nevin N. Weinberg, Phil Arras +2
Tidal interactions in coalescing binary neutron stars modify the dynamics of the inspiral and hence imprint a signature on their gravitational wave (GW) signals in the form of an e…
Periastron precession effect of -mode dynamical tides on gravitational waves from eccentric double white dwarfs
Shu Yan Lau, Kent Yagi, Phil Arras
The dynamical tide can play an important role in the orbital motion of close eccentric double white dwarf binaries. As the launching of the space-based gravitational-wave detector,…
I-Love-Q Relations for Realistic White Dwarfs
Andrew Taylor, Kent Yagi, Phil Arras
The space-borne gravitational wave interferometer, LISA, is expected to detect signals from numerous binary white dwarfs. At small orbital separation, rapid rotation and large tida…
Nonlinear mode coupling in rotating stars and the r-mode instability in neutron stars
A. Katrin Schenk, Phil Arras, Eanna E. Flanagan +2
We develop the formalism required to study the nonlinear interaction of modes in rotating Newtonian stars in the weakly nonlinear regime. The formalism simplifies and extends previ…
