Newtonian Gravitational Wave Chirp Signal from Merger of a Compact Binary
Newtonian Gravitational Wave Chirp Signal from Merger of a Compact Binary
This Demonstration shows the gravitational wave emitted before the merger of two compact objects orbiting around each other, such as a neutron star and a black hole. Only the leading-order Newtonian approximation is considered. The waveform is a chirp, which consists of increasing wave amplitude with time (first figure) and increasing frequency with time (second figure). The chirp can be heard by playing the sound of the waveform.
