Gravitational Lensing of Gravitational Waves from Merging Neutron Star Binaries.

We discuss the gravitational lensing of gravitational waves from merging neutron star binaries, in the context of advanced LIGO type gravitational wave detectors. We consider properties of the expected observational data with cut on the signal-to-noise ratio ρ, i.e., ρ > ρ0. An advanced LIGO should see unlensed inspiral events with a redshift distribution with cut-off at a redshift zmax < 1 for...

Secular Bar-Mode Evolution and Gravitational Waves From Neutron Stars

The secular instability and nonlinear evolution of the m = 2 f-mode (barmode) driven by gravitational radiation reaction in a rapidly rotating, newly formed neutron star are reviewed. There are two types of rotating bars which generate quite different gravitational waveforms: those with large internal rotation relative to the bar figure (Dedekind-like bars) have GW frequency sweeping downward d...

Gravitational waves from neutron stars

Breaking strain of neutron star crust and gravitational waves.

Mountains on rapidly rotating neutron stars efficiently radiate gravitational waves. The maximum possible size of these mountains depends on the breaking strain of the neutron star crust. With multimillion ion molecular dynamics simulations of Coulomb solids representing the crust, we show that the breaking strain of pure single crystals is very large and that impurities, defects, and grain bou...
