AT 2019qiz
Tidal distribution event
From Wikipedia, the free encyclopedia
AT 2019qiz is a tidal disruption event (TDE) that occurred at a distance of 215 millions light years (65 megaparsec), from Earth.[1] It is the nearest TDE discovered to date.[2] It was discovered in September 2019 by observations in ultraviolet, optical, X-ray and radio wavelengths made at the European Southern Observatory (ESO)[3] situated in Chile and was presented in October 2020 by research published in the monthly notices of the Royal Astronomical Society. It involves a star with a sun-like mass and a black hole with a mass of around 106 solar masses. The TDE appears very young and increasing in brightness. The encounter tore away half of the mass of the star and threw debris at a speed of 10,000 km/s, comparable to that observed in supernova explosions.[4][1]
