  • In its final year of inspiral, a stellar mass (1-10 M⊙) body orbits a massive (105-107 M⊙) compact object about 105 times, spiralling from several Schwarzschild radii to the last stable orbit. These orbits are deep in the massive object's strong field, so the gravitational waves that they produce probe the strong-field nature of the object's spacetime. Measuring these waves can, in principle, be used to `map' this spacetime, allowing observers to test whether the object is a black hole or… CONTINUE READING
