The axis on the bottom of the graph depicts frequencies between 20-1000 Hz which are sound waves. Again, how can a sound wave (gravity waves) propagate in the near vacuum of stellar space that is vacuum?

"On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0×10^−21." (Abstract).Abbott, B. P. Observation of Gravitational Waves from a Binary Black Hole Merger. Physical Review Letters. 116, 061102. 2016

Can you explain how electromagnetic stellar gravity waves (GR) form the effects of sound waves at the LIGO observatory?
