Suara.com – Ke Astronomer Found a new way to calculate size Black hole Supermassive, namely by studying the diet of this giant object.
Scientists have long observed luminous patterns in the brightness of accretion disks, as matter is pulled up by the black hole’s gravitational force.
However, experts do not yet know what causes the blinking pattern.
Now, a team of astronomers has determined that the disk’s accumulated luminosity is related to the mass of the black hole inside.

“We believe the same technique applies to many things, such as objects smaller than black holes,” said Yu Shen, the study’s lead author and astronomer at the University of Urbana-Champaign in Illinois.
To check the relationship between size Supermassive black hole And the light emitted from the disk, scientists selected 67 supermassive black holes.
Each previously estimated mass is between 10,000 and 10 billion times the mass of the Sun.
When the data showed a correlation, the researchers decided to look at a very small object with a white dwarf’s accretion disk.
Colin Burke, a professor of astronomy and graduate student at the University of Illinois at Urbana-Champaign, said: “There is now a relationship between the luminous pattern and the mass of the central accretion object.
