For 10 points, identify this phenomenon which is sought after byexperiments like LIGO, and which is produced by the acceleration of massive bodies.
The counterintuitive growth of r-modes in the CFS instability results from an object occupying a more favorable energeticstate despite losses due to this phenomenon. In cosmological string theory, loops formed from line-like topological defectsdisintegrate as a consequence of this phenomenon. In the quadrupole approximation, the luminosity of this phenomenon isproportional to the sum of the squares of the third time derivatives of the components of the quadrupole tensor. This phenomenongenerates the B-mode polarization in the cosmic microwave background. The so-called "period gap" observed incataclysmic variables is believed to be due to a transition from magnetic braking as a mechanism of angular momentum lossto this phenomenon. The orbit of the Hulse-Taylor binary is decaying as a consequence of this phenomenon, which resultsfrom propagating solutions to Einstein's Âfield equations.
