Luminous red nova
More luminous red novae were found after the discovery. Researchers found V1309 Scorpii in 2008. The star system was a contact binary. Researchers were studying it for six years before it merged and exploded. In 2015, two different luminous red novae were found. One was in the Andromeda galaxy, and the other was in the Pinwheel galaxy. Astronomers think that in 2022, KIC 9832227 will merge and become a new luminous red nova. This star system is 1800 light years away from the Sun. A team from Calvin College found that the orbital period of the star system was slowing down and that the stars were coming closer to each other.
