Hulse–Taylor Binary

The Hulse–Taylor binary is a pair of neutron stars named after Joseph Hulse and Russell A. Taylor, who discovered them in 1974. They orbit each other closely, and their gravitational interaction is so strong that it causes them to emit detectable gravitational waves. This system has provided critical evidence for the existence of these waves, supporting a key prediction of Einstein's General Theory of Relativity. The study of the Hulse–Taylor binary has deepened our understanding of the universe, particularly in the areas of stellar evolution and gravitational wave astronomy.
