From article:

"Short-period white dwarf binaries are interesting because they generate gravitational waves. One of the new discoveries emits so much gravitational waves that it is a new verification source for the upcoming Laser Interferometer Space Antenna—a gravitational wave satellite," Kilic said.

The same can be said for Hulse-Taylor Neutron-Star Binary System dynamics.

Yet gravitational waves from these relatively nearby grav-wave sources have yet to be detected. Why?

That is the question that should be answered by those claiming to have detected grav-waves from sources BILLION(s) of lightyears distance but have not detected any from THESE MUCH CLOSER sources.

So, would anyone 'believing' a-LIGO claims care to 'do the maths' and post it here to explain how grav-waves can remain 'detectable' over 'background noise' after BILLION(s) of lightyears propagation, yet NO grav-waves detected from these Binary NS/WD sources close to/within our MW galaxy?

Thanks. :)

Good Point.
In May of 2014 I experienced an exceptional calmness and was surprised to find that the imaginary 'gravity waves' were claimed to have been identified on that day. Nope. Magnetic solitons must be the responsible party.

As an answer to why some are not detected and some are, it is not just the magnitude of the waves, it also is the frequency of the waves. If you have something with a longer wavelength (lower frequency) then you have to have legs of the interferometer longer. If you notice, they could only detect the waves as they were entering the audible frequency range. That is a much shorter wavelength than something like a binary with a frequency in the per/hour range. Look up the "chirp" for the detected waves to see how their frequency changed as the black holes collided. If it was two white dwarfs that were closer that collided they could have detected that. The space interferometers will have legs that are hundreds of kilometers long and they will be able to detect lower frequency waves such as the orbiting white dwarf stars.
