WD J0651+2844 is a white dwarf binary star system composed of two white dwarfs.[1] They are approximately 120,000 km apart and complete an orbit around their barycenter in less than 13 minutes.[2] This produces an eclipse every 6 minutes. This makes it possible to gather enough data to produce extremely accurate predictions of each future eclipse. The eclipse times deviate from the time predicted in a way consistent with gravitational waves.[3][4][5]
