Strange new stars created by collisions of white dwarfs are like we have never seen before



The central star in the IRAS 00500 + 6713 nebula may be a new type. Stars and nebulae observed by ESA’s XMM-Newtown X-ray telescope glow green in this image.

In the near future, our sun will become a white dwarf star, itself a dense, remnant remains. There are many white dwarfs lurking in the universe, Sometimes they collide. Astronomers believe that the merger of two white dwarfs may have produced a previously invisible star, a zombie furnace rising from death. When observed with X-rays, the nebula surrounding the new star glowed an eye-catching green due to the effect of neon gas.

The European Space Agency released an unusual view of the star on Monday. He said: “The image shows a new X-ray star that has never appeared before.”

; The star J005311 was found in a dense cloud of dust and gas-a nebula. -Known as IRAS 00500 + 6713.

of Stars first caught the attention of astronomers in 2019, This is obviously a freak. In a statement on Monday, ESA said: “At the time, astronomers had reported that the object had high wind speeds and was too bright and therefore too large to be an ordinary white dwarf.”

A team led by astrophysicist Lidia Oskinova of the University of Potsdam in Germany used ESA’s XMM-Newton X-ray telescope to make a new observation of stars. The team published a paper on stars in the journal Astronomy and Astrophysics in December.

White dwarf collisions may cause damage to the stars involved, but these white dwarfs do not follow the typical script. According to the European Space Agency, the research team recommends: “What we see in the image is a new type of X-ray source that combines two white dwarfs.”

X-ray telescopes such as XMM-Newton allow us to observe objects in the universe in a different way from optical telescopes. Hubble of NASA.ESA said: “Many celestial bodies produce X-rays in extremely violent processes.” XMM-Newton is able to see this action and helps us nebula, galaxy, Supernovae and black holes.

This new X-ray study can provide a more comprehensive understanding of the state of stars in the nebula. Its fate is sealed. The European Space Agency said it is very unstable and is likely to collapse into a neutron star, which is what happens when the star runs out of fuel at the end of its life within 10,000 years. But its duration will be glorious.
