Mysterious ‘blink’ object detected near the center of our galaxy



There is a foreign body near the center of the galaxy.

About 25,000 light-years from Earth, astronomers have discovered a strange star that almost blinked from existence months before it appeared.

Astronomers believe the star, named VVV-WIT-08, may belong to a new constellation: a giant beast more than 100 times the sun’s size, obscured by a mysterious object that orbits every few decades.

The weirdly dim signature star is an endless charm. Although most of the area is quite empty. But there was a reason with all the things that existed. Some will line up in such a way that the stars will occasionally dim from our ground view.

It’s not always easy to tell what that is. Giant planet? Space dust? Debris from scattered objects? Cosmic dragon?

7;s case is nonsense. Even if other stars have the same depressing light. But no star is as deep as this. Astronomers think the culprit could be another star or planet surrounded by a dense disk of dust on a long orbit around VVV-WIT-08, which completely covers the star as it passes in front of us.

Astronomer Sergey Koposov from the University of Edinburgh in Scotland said: “Surprisingly, we recently observed a large, elongated dark object passing between us and a distant star. And we can guess what its origins are.”

A replica of an orbital mate with a gigantic disk is unprecedented. One famous and well-known example is Epsilon Orique, a giant star with a saucer in a 27-year orbit that dims the star by about 50 percent for up to 730 days.

Then there’s the TYC 2505-672-1 system, a red giant whose dust companion lies on a 69-year orbit that obscures the star for a period of 3.5 years.

The survey picked up VVV-WIT-08 (“WIT” stands for “what is this?” because astronomers are so good at it). The VISTA variable in the Via Lactea (VVV) survey gathered a few other candidates who looked like will show the same behavior As information about those stars is not as complete as VVV-WIT-08’s, there is no explanation.

We know that stellar characteristics are not an error. The dimming was also observed in gravitational lens experiments using the Warsaw Telescope in Chile. This means it’s not a mistake. (although it must be a very strange mistake)

The data showed that the dimming event lasted about 200 days with a nearly symmetrical light curve. This caused the star’s light to go out by up to 97 percent. The object density required in that region of that region for the accidental alignment of two random objects was much higher than observed. Therefore, the team believed the two objects were bound by gravity.

orbital period unknown But it takes at least a few decades according to mathematical models.

And the findings suggest that such a system may not be uncommon.

University astronomer Leigh Smith said: “There is still a lot to be found. But the challenge now is to find out what the hidden companion is. And why are they surrounded by discs? even orbiting very large stars” of Cambridge.

“In doing so We may learn something new about the evolution of this type of system.”

The research was published in Monthly announcement of the Royal Astronomical Society.
