Capturing the moment when a black hole swallows stars

On October 12 (local time), the European Southern Observatory ESO released a paper that observed a tidal disruption event, a tidal disruption event (TDE), which collapsed when a celestial body approaching a black hole was torn off, along with images and videos.

ESO said on October 12 that a known tidal destruction event was discovered in September 2019 at AT2019qiz, close to Earth. Discovered in the spiral galaxy of Eridanus, AT2019qiz was not only close to Earth, it was just alive, and it was quite clearly observable.

When the black hole and the celestial body get closer and the tidal destruction event begins, the celestial body is elongated and elongated like spaghetti due to strong gravity. ESO has been observing AT2019qiz for 6 months and has made an image of the noodle effect phenomenon and released it through Twitter and YouTube.

The orange sphere is a star as mass as the sun. When the star approaches a black hole with a mass of more than 1 million times, the noodle effect occurs, and the star is elongated and swallowed by the black hole. It is said that the speed of matter at which stars are swallowed by a black hole reaches 10,000 kilometers per second. Half the mass of the star was swallowed up by the black hole, and the other half was emitted toward the outside.

It is believed that when the noodle effect occurs, it explodes and generates strong electromagnetic waves. However, since the celestial debris swallowed by the black hole covers the light like a curtain, it has not been possible to reliably observe the tidal destruction event.

When a black hole swallows a star, a powerful explosion occurs that blocks the view.This time, by catching the moment when the black hole began to emit matter at a rapid rate, by detecting a tidal destruction event early, the black hole actually entwined a curtain of dust and debris. Explained that they could.

The findings help us understand how matter behaves in supergiant black holes and extreme gravitational environments. Related information can be found here .
