Astronomers are expecting evidence of Dark Matter Particles in Betelgeuse

The imaginary particles Axions might describes about the presence of dark matter. But in the cores of star sometimes it might interact with the other normal matter. Research carried out by a team of physicists to find the evidence for the presence of Axions in Betelgeuse but they didn’t find anything there. It doesn’t mean that axions are not present in the Betelgeuse or exists it’s just that they are hard to find.

The component in the universe that makes 85% of the mass which is referred to as dark matter. They are just form of particles that are unknown to the standard model of physics and also it barely interacts with the photons or other normal matter. There are so many candidates for the dark matter and from them one family is known as axions that are projected for so many theories of high energies of physics.

If we take a quick look at axions that fits the bill, they are very small, lightweight and also never interacts with light or other matter and this kind of axions are known as ultralight as it can easily get detected through Primakoff effect process. This process works as if a photon is placed in a super strong magnetic field it can sometimes turn as an axion. As the axions doesn’t interacts with the other matter they are free to travel wherever it wants and if they run across another magnetic field it gives away the existence of axion and the Primakoff effect. There will be strong magnetic fields in the cores of the stars and they might get termed as axion factories. What these axion factories will do they emit the x-ray radiation and also they want to use the sun as a laboratory they are using the released x-rays for their own reason.

Here Betelgeuse being a giant star nearing its end of life has a different story. It barely ever emits x-rays and also it is much cooler than the sun. Betelgeuse have to emit measureable amount of x-rays if there are axions and Primakoff effect is correct. Researcher team from MIT exactly did this but they didn’t found anything. Kerstin Perez, assistant professor of physics at MIT said that if you really want to see those light particles you have to think something else that is out of the box that gives you the axion signals.
