Gravitational Wave Detectors: How They Work

WebUsing gravitational waves, scientists could pinpoint and then record new light-based observations indicating that heavy elements, such as lead and gold, are created in these … WebThe next question that arises is how the period of a gravitational wave is related to that of the motion of the source. If the binaries are in a circular orbit, the resulting gravitational waves have a frequency that is twice that of the binary system--that is, the period of the gravitational wave is one half of the orbital period.

WebA gravitational wave may travel at the speed c, but also below depending on the amplitude. Essentially, it employs spacetime itself as a medium. A particular wave metric: d s 2 = d t 2 − d r 2 + H ( t − r, x 1, x 2) ( d t − d r) 2 − d ( x 1) 2 − d ( x 2) 2 Although the waves from the Earth–Sun system are minuscule, astronomers can point to other sources for which the radiation should be substantial. One important example is the Hulse–Taylor binary – a pair of stars, one of which is a pulsar. The characteristics of their orbit can be deduced from the Doppler shifting of radio signals given off by the pulsar. Each of the stars is about 1.4 …
