About: AT2019qiz

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

AT2019qiz is a tidal disruption event (TDE) that occurred at a distance of 215 millions light years (65 megaparsec), from Earth. It is the nearest TDE discovered to date. It was discovered in September 2019 by observations in ultraviolet, optical, X-ray and radio wavelengths made at the European Southern Observatory (ESO) 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.

  • AT 2019qiz est un événement transitoire associé à un événement de rupture par effet de marée. Détecté dans le spectre optique le 19 septembre 2019 à 11 heures, 59 minutes et 43 secondes (heure française) par le Zwicky Transient Facility (ZTF), avec une magnitude apparente maximale de 17.81. AT 2019qiz est l'événement de rupture par effet de marée le proche connu, sa distance est estimée à ~250 millions d'a.l. et il est originaire de la galaxie PGC 980815, leurs décalages vers le rouge respectifs étant le même. Depuis sa détection par le ZTF, il a été observé dans quasi tout le spectre électromagnétique, excluant les rayons gamma. Après sa détection en 2019 et toutes les analyses effectuées, les scientifiques le révèlent au monde dans un article publié en octobre 2020 dans la revue scientifique Royal Astronomical Society. (fr)
