Scientists have seen a rare burst of light from the star since it was lifted by a black hole.
The unusual “tidal disturbance phenomenon” was visible in telescopes around the world. It appeared as the brightest flame of 21 days, the closest registration of its kind, just 215 million light-years away.
Such phenomena occur when a star approaches a black hole, and is pulled by its extreme gravity.
As the star sucks, it undergoes a process called “spaghetification”, where the star is cut into thin strips, some of which fall into a black hole.
When that happens, energy flares are released that fly through the universe, enabling the process to be discovered by distant astronomers.
Lead lecturer of the University and research fellow of the Royal Astronomical Society. Matt Nicole said, “Sucking a nearby star’s black hole ‘sounds like science fiction. But the same thing happens in the event of a tidal collapse. Birmingham.” A description of what happens when a star is eaten by a monster. We were able to investigate. “
They were able to see it through telescopes around the world – the European Southern Observatory’s very large telescope and the New Technol les G Telescope, the Las Cambres Observatory Global Telescope Network, and Neil Gehrel’s Swift Satellite – over a period of six months. Became bright and then faded.
Such a scenario is usually not possible because dust and debris can trigger tidal rupture events, which are already very rare. Which has investigated the nature of those flames which is very difficult.
“When a black hole eats up a star, it can erupt out of a massive explosion of material that obstructs our vision,” said Samantha Oates at the University of Birmingham. “This is because the energy emitted like a black hole eats up the stellar material.”
Astronomers at TTC. Namna could see this better than before, as it was found soon after the star was cut.
An ESO Fellow at the Institute of Astronomy, Cambridge University, Chile, Santiago, Chile, UK, says, “Some celestial surveys detected emissions from a new tidal disturbance very quickly after a star erupted.” Work carried out. “We immediately pointed to ground-based and space telescopes pointing in that direction to see how light was generated.”
Let both flames and debris see and understand it in a way that would normally envelop it.
For the first time, astronomers were able to see ultraviolet, optical, X-ray and radio light that came out of the event and could see a direct connection between the material from the star and the bright flames emitted directly from it, as it swallowed. Black hole.
“Observations showed that the star had almost the same mass as our own sun and lost about half of it in a black hole, more than a million times larger,” said Nicole, who is also a visiting researcher here. University of Edinburgh.
They could also see the clouds of debris rising and covering the process – another unprecedented point of view.
“Because we caught it early, we actually saw a curtain of dust and debris being pulled because a powerful flow of material with a velocity of up to 10,000 km / cm was initiated through the black hole,” said Kate Alexander, NASA’s Einstein Fellow at NASA’s Northwest. . U.S. In the University. “This unique ‘peek behind the scenes’ will provide the first opportunity to direct the origins of obscure content and follow in real time how it involves black holes.”
