NASA’s Hubble Space Telescope Record in detail the last moments of a star as it is devoured by a black hole.
The agency said the suit transformed the star into a donut shape in the process.
When a star gets close enough, the black hole’s gravitational grip violently separates it, emitting intense radiation in what’s known as a “tidal disturbance event.”
Astronomers are using the telescope to better understand what’s going on, using its strong ultraviolet sensitivity to study the light from the “stellar snack event” AT2022dsb.
The star is located 300 million light-years away, in the heart of galaxy ESO 583-G004.
Astronomers have detected nearly 100 tidal disturbance events around black holes using multiple telescopes.
The agency recently reported that another such event was detected by a high-energy space observatory in March 2021.
“We’re excited to be able to get these details about what the debris is doing. Tidal events can tell us a lot about a black hole,” said Emily Engelthaler of the Center for Astrophysics | He said in a statement to Harvard and the Smithsonian.
to any galaxy A massive supermassive black hole At the center, stellar rupture is estimated to occur only a few times every 100,000 years.
This AT2022dsb event was first detected on March 1, 2022, by the All-Sky Instrument Survey of Supernovae, a network of ground-based telescopes.
The collision was close enough to Earth and bright enough for ultraviolet spectroscopy over a longer period of time than usual.
Usually these events are hard to notice. You will likely get some feedback early on in the turmoil when it is really evident. Our program is different because it is designed to look at some tidal events over the course of a year to see what happens,” explained Peter Maksim of the Astrophysical Center. We saw this early enough that we could observe it in the very intense phases of black hole accretion. We saw a decrease in the accretion rate as decreases over time.”
The data is interpreted as coming from the circular figure The gas region that was once a star.
The region known as the torus orbits a black hole at its centre.
