Resonant Tidal Responses in Rotating Fluid Bodies: Global Modes Hidden beneath Localized Wave Beams

Tidal dissipation in rotating fluid bodies: a simplified model

We study the tidal forcing, propagation and dissipation of linear inertial waves in a rotating fluid body. The intentionally simplified model involves a perfectly rigid core surrounded by a deep ocean consisting of a homogeneous incompressible fluid. Centrifugal effects are neglected, but the Coriolis force is considered in full, and dissipation occurs through viscous or frictional forces. The ...

Resonant Tidal Excitations of Rotating Neutron Stars in Coalescing Binaries

In a coalescing neutron star-neutron star or neutron star-black hole binary, oscillation modes of the neutron star can be resonantly excited by the companion during the final minutes of the binary inspiral, when the orbital frequency sweeps up from a few Hertz to a few thousand Hertz. The resulting resonant energy transfer between the orbit and the neutron star speeds up or slows down the inspi...

Mechanism of Edge Localized Modes mitigation by Resonant Magnetic Perturbations

Distinct quasiperiodic modes with like symmetry in a rotating fluid.

Tidal and Tidal-Resonant Effects in Coalescing Binaries

Tidal and tidal-resonant effects in coalescing compact binary systems are investigated by direct numerical integration of the equations of motion. For the stars polytropic models are used. The tidal effects are found to be dominated by the (non-resonant) f -modes. The effect of the g-mode-tidal resonances is obtained. The tidal interaction is shown to be of interest especially for lowmass binar...
