The collision of neutron stars produces gravitational waves from "summary" of The Science of Interstellar by Kip Thorne

When two neutron stars spiral into each other and collide, the event generates a cataclysmic release of energy in the form of gravitational waves. These waves are ripples in the fabric of spacetime itself, carrying information about the violent merger across the universe at the speed of light. Neutron stars are incredibly dense remnants of massive stars that have exploded in supernovae, packing more mass than the sun into a sphere just a few kilometers across. As the neutron stars spiral closer and closer together due to their mutual gravitational attraction, they eventually reach a point where the tidal forces between them become so strong that they deform and break apart. This process, known as tidal disruption, releases a tremendous amount of energy in the form of gravitational waves. These waves propagate outward in all directions, spreading the signal of the collision far and wide. The detection of gravitational waves from the collision of neutron stars represents a monumental achievement in astrophysics, opening a new window onto the universe and allowing scientists to probe some of the most extreme phenomena in the cosmos. By studying the signals emitted during these mergers, researchers can learn valuable information about the properties of neutron stars, the behavior of matter under extreme conditions, and the nature of gravity itself. The collision of neutron stars is a rare event, occurring only once every few hundred thousand years in a typical galaxy. However, with the advent of advanced detectors like the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo interferometer, scientists now have the ability to detect these elusive signals and unlock the secrets they hold. By analyzing the gravitational waves produced by neutron star mergers, researchers can gain insights into the origins of heavy elements like gold and platinum, the structure of neutron stars, and the behavior of matter under extreme conditions. In summary, the collision of neutron stars represents a unique and powerful source of gravitational waves, providing scientists with a wealth of information about some of the most extreme phenomena in the universe. By studying these signals, researchers can deepen their understanding of neutron stars, black holes, and the fundamental nature of spacetime itself.
