Gravitational radiation of stellar configurations consisting of incompressible fluid

This article discusses the gravitational radiation of rotating and oscillating stellar configurations with an incompressible fluid equation of state. The method used here makes it possible to determine the frequencies and amplitudes of the gravitational waves for arbitrary values of the central densities. At the densities corresponding to neutron stars, the major parameters of the gravitational radiation are consistent with previous results from more realistic models. Depending on the central density, stellar configurations with an incompressible fluid can emit gravitational waves over a wide range of frequencies, from 10−2 to 104 Hz.
