Astronomy enthusiasts discover 95 brown dwarfs near Earth


Astronomy enthusiasts discovered near Earth 95 brown dwarfs as failed cold stars, in an attempt to discover a hypothetical ninth planet in the solar system, and astronomer at the American National Laboratory for Optical Astronomy and Infrared Astronomy, Aaron Messner, said, “The discovery of cold stars helps us to Understanding how planets form outside the solar system and the structure of their gaseous atmosphere. “

It is noteworthy that all stars in the universe originate in dense clots consisting of dust and gas, then compress them, which leads to a rise in temperature and pressure inside them and the launch of thermonuclear reactions in their interior, according to Russia today.

And such a process starts, according to astronomers, inside large cosmic objects whose core weighs 73 times the weight of Jupiter’s nucleus. In the event that the embryo of the star does not reach the aforementioned weight, then it turns into a brown dwarf or a failed star that gradually turns off as its core cools, and the astronomers found first brown dwarfs in 1995, and in recent times they made sure that it has metal clouds and a gas envelope that generates weather, and this matter is pushed by some Scientists have come to believe that brown dwarfs are not stars but giant planets.

For years, Messner and his colleagues have been studying brown dwarfs as part of the “Backyard Worlds: Planet 9” project, in which professional astronomers and astronomers alike participate. The goal of the project was first to discover the hypothetical ninth planet “X” in the solar system, whose traces were found in 2003. 2016 Russian astronomer Konstantin Batygin, and American astronomer, Michael Brown by WISE.

Project participants study photographs of areas of space captured by the telescope in an attempt to discover space objects whose locations change over time. And they analyzed 30 thousand photographs and discovered more than a thousand previously unknown space objects inside and outside the solar system.

The astronomers developed a catalog of the coldest brown dwarfs near Earth that belong to the Y-spectrum waves that include at least 10 cold dwarfs whose surface temperature does not exceed a few hundred degrees Celsius, and it showed the information that professional and non-professional astronomers were able to obtain in the framework of the Backyard Worlds project Planet 9: that 95 cool brown dwarfs are located near Earth, that is, at a distance of between 30 and 60 light years.
