Quadrupole formula
text:
In general relativity, the quadrupole formula describes the rate at which gravitational waves are emitted from a system of masses based on the change of the (mass) quadrupole moment. The formula reads where h ¯ i j is the spatial part of the trace reversed perturbation of the metric, i.e. the gravitational wave. G is the gravitational constant, c the speed of light in vacuum, and I i j is the mass quadrupole moment. It is useful to express the gravitational wave strain in the transverse traceles
