The black hole, called V404 Cygni, has been observed in a triple system, gravitationally bound to two stars. This shows that some binary systems with a black hole and an ordinary star may have initially formed as a triple system, with the black hole subsequently swallowing one of the stars, a gentler process than supernovae.
