Eight of the hottest stars in the universe have been discovered

An international team of astronomers has announced that they have discovered eight of the hottest stars ever found in the universe, all of which have surface temperatures above 100,000 degrees Celsius. The hottest star is reaching them 180,000 points, compared to only 5,800 degrees that the surface of our Sun has. All belong to the category of white dwarfs.

The researchers from Britain, Germany, South Africa and Australia, led by astronomer Simon Jeffery of the Armagh Observatory and Planetarium in Northern Ireland, who made the relevant publication in the journal “Monthly Notices” of the British Royal Astronomical Society, used for their observations the South African Large Telescope (SALT), the largest optical telescope in the southern hemisphere with a mirror 10 by 11 meters.

One of the new hot stars is the central star of a previously unknown planetary nebula that is one light-year across. Two others are variable stars of varying brightness. And eight stars they are in an advanced stage of their life cycle and are nearing their end as white dwarfs. The stars in question are about the size of Earth, but a million times more massive, almost similar to that of the Sun. They are the densest stars composed of normal matter.

Jeffery stated that “stars with temperatures of 100,000 degrees Celsius or more are incredibly rare. It was a real surprise that we found so many such stars. These new discoveries will help improve our understanding of the final stages of stellar evolution.”
