Gravitational Radiation from Nonaxisymmetric Spherical Couette Flow in a Neutron Star

Abstract

The gravitational-wave signal generated by global, nonaxisymmetric shear flows in a neutron star is calculated numerically by integrating the incompressible Navier-Stokes equation in a spherical, differentially rotating shell. At Reynolds numbers Re 3#10 the laminar Stokes flow is unstable, and helical, oscillating Taylor-Görtler vortices develop. The… (More)
