Australian scientists have found the coldest among rare ultracold brown dwarfs with radio emission

Scientists from Australia have analyzed a group of ultracool brown dwarfs that possess

These are very rare stars in our Universe, accounting for about 10% of cinnamon dwarfs.

What is known

The researchers were able to determine whichultracold brown dwarfs emitting radio waves, is the coldest. It turned out to be a star with the catalog number T8 Dwarf WISE J062309.94-045624.6.

Our hero is about 37 light years away.from the earth. Caltech scientists discovered it 12 years ago. As it became known, the temperature on the surface of T8 Dwarf WISE J062309.94-045624.6 is only 425 degrees Celsius, i.e. 10 times lower than on the Sun.

The star is tens or even hundreds of times smaller thanSun. Scientists were unable to determine the exact mass of T8 Dwarf WISE J062309.94-045624.6, but found that it is 4-44 more than that of Jupiter. The radius of a brown dwarf is 0.65-0.95 that of Jupiter.

The rarity of such stars lies in the presence of radio emission. Usually brown dwarfs do not have it. This is due to the fact that the dynamics of such stars does not create magnetic fields.
