Neutron stars usually spin very rapidly, so the asymmetric distribution of mass would deform space - time and produce a continuous gravitational - wave signal in
the shape of a sine wave, which would radiate energy and slow down the star's spin.

I would be interested to see whether Rossander can as easily achieve 99.997 % with small adjustments to his overfitted model, whose ten independent
shape parameters (I needed only 3) make it simply a bunch
of sine waves that could just as well have been obtained using a Fourier transform.
