Jakarta, CNBC Indonesia – A study found a scenario where a black hole swallowed a star. Discovered black holes will result in what astronomers call a ‘tidal disturbance event’.
The star will rupture followed by a burst of radiation that can exceed the combined light of any star in the parent galaxy. This goes on for months or even years.
The findings come from a paper by a team of astronomers led by Sixiang Wen, a postdoctoral researcher at the University of Arizona Steward Observatory. They used X-Rays emitted by a tidal disturbance event otherwise known as J2150.
This was done by the research team to measure the mass and spin of the black hole. The object is of a certain type with medium mass and escapes observation.
“The fact that we can capture a black hole as it devours a star offers an extraordinary opportunity to observe what is invisible,” said Ann Zabludoof, an Arizona astronomy professor and co-author on the paper. .
“Not only that, by analyzing the light we can understand the elusive black hole category, which probably explains most of the black holes at the center of galaxies.”
Using the return of X-ray data from J2150 and comparing it with advanced theoretical models, the researchers demonstrated that this light did indeed originate from the confluence of a star and an intermediate-mass black hole.
For information, medium-mass black holes are estimated to weigh approximately 10 thousand times.
“X-ray emission from the interior formed by the debris of a dead star allowed us to infer the mass and spin of the black hole and classify it as an intermediate black hole,” said Wen.
Nicholas Stone, who is also a co-author, revealed that because of modern astronomical observations, he was finally able to find out the center of all galaxies that were the same size or larger than the Milky Way and also had very large black holes.
“This object is from 1 million to 10 billion times the mass of our Sun and becomes a powerful source of electromagnetic radiation when too much interstellar gas is far into its surroundings,” said the senior lecturer at Hebrew University.
