There is nothing like the strange new star that made the white dwarf collide



The nebula may be a new central type in the IRAS 00500 + 6713. The stars and nebulae were seen in ESA’s XMM-Newtown X-ray telescope, which shines green in this image.

In the distant future, our sun will become a white dwarf star, a gaa, its own dead remnant. There are many white dwarfs hidden in the universe and, Sometimes they collide. Astronomers believe that the merger of the two white dwarfs may have previously produced an invisible type of star, killing a type of zombie furnace. When viewed in X-ray light, the nebula around this constellation glows green thanks to neon gas.

The European Space Agency on Monday released an unusual view of the star, saying “this image shows a new type of star that has never been seen in X-ray light before.” The star, 005311, is found in a ga cloud cloud of dust and gas – a nebula – known as IRAS 00500 + 6713.

This The star first came to the attention of astronomers in 2019, And it was obviously a dubbed ball. “At the time, astronomers had already reported that the white object had very high wind speeds and was very bright, and therefore large enough to become a normal white dwarf,” the ESA said in a statement Monday.

A team led by Lydia Oskinova, an astrophysicist at the University of Potsdam in Germany, re-examined the star using ESA’s XMM-Newton X-ray telescope. The team published a paper on the star in the journal Astronomy and Astrophysics in December.

White dwarf collisions can be devastating for the stars involved, but these white dwarfs do not follow the usual playbook. According to ESA, the team suggests that “the image we see in it is a new type of X-ray source powered by a merger of two white dwarfs.”

X-ray telescopes like XMM-Newton Let’s look at cosmic objects differently than optical telescopes. NASA’s Hubble. “Many celestial bodies produce X-rays in extremely violent processes,” the ESA said. XMM-Newton is able to see this action and contribute to our understanding Nebula, Galaxies, Supernovae and black holes.

The new X-ray study gives a more complete picture of what is happening to the stars in the nebula. His fate is sealed. The ESA said it is very unstable and will probably fall into a neutron star – which is what happens when a star runs out of fuel at the end of its life – in 10,000 years. But it will be glorious when it lasts.
