Discovery … about one of the closest stars to Earth and its relationship to dark matter


The star called “Bethel Gemini” appears as a bright red dot. It is a well-studied star. It is close in cosmic terms, only 520 light years from Earth. It drew attention to it in the past when it began to mysteriously obscure, which led some researchers to believe That he might be preparing to explode.

According to the “RT” website, scientists say that because it is a big and hot star, it may also be an ideal place to find axons, and these axions are particles that can contain a million or even a billionth of the mass of an electron, which are ideal candidates for the formation of dark matter. , The mysterious matter that greatly exceeds the ordinary matter in the universe but whose nature is still largely undetermined.

Also, since they are dark matter, axons should not interact much with luminous particles, but according to some theories, there is a small possibility that photons, or light particles, can be turned back and forth into axes in the presence of a strong magnetic field, according to Mengjiao Xiao. A physicist at the Massachusetts Institute of Technology (MIT) in Cambridge, for Live Science.

The thermonuclear core of the star is a good place to find abundant quantities of photons and magnetism, and “Betelgeuse”, which has a mass of 20 times the mass of the sun, can be envisioned as “what we call the Axion factory.”

The “Prospector of Gemini” is in the stage of life where it should not emit much X-ray light, so any radiation detected from it may indicate the presence of the interlocutor.

And Xiao and his colleagues used the Array of NASA’s Nuclear Spectroscopy Telescope (Nostar) to search for an X-ray fingerprint from “Betelgeuse”, even though they saw nothing beyond what was expected from normal astrophysical processes such as a small amount of X-rays.

The results, which Xiao presented on April 20 at the American Physical Society meeting, indicate that photons and axes are at least three times less likely than previously thought.

And even if researchers see unexpected x-rays coming from a star, that won’t necessarily indicate that the axes are real, and scientists still have to rule out many non-dark matter interpretations of the signal before switching to new physics.

It is possible that the axons, if they are found someday, could help astronomers better understand Gemini’s socket, Xiao said.
