Details

When orbiting compact binary objects are approaching each other, the resulting gravitational wave can be described with the leading-order Newtonian chirp waveform. This waveform depends only on:

the chirp mass , where and are the component masses of the binary system, and

the distance of the binary from the point of observation.

We assume that the distance of the binary from the point of observation is 1 Mpc. The chirp duration measured from 10 Hz to the frequency of merger is smaller for more massive binary objects.
