184 light years from the solar "twin" estimation star :: Daily Economy News


It is similar in magnitude, brightness, chemical composition to type G … Note that planets such as Earth

The star to be "twin" is 184 light-years away because it is similar to the Sun.

It has been reported to the dorms that it is almost certain that this star, named "HD186302", was not a twin sun, but at least a brother of the sun that was never discovered.

According to ScienceAlert, a research team headed by Professor Vardan Adybeckan of the Institute of Astrophysics and Space Sciences (IA) on November 20, "special" star HD186302, resembling the sun, According to the latest edition of the International Journal of Astronomy and Astrophysics.

Most stars are born with other stars in huge clouds of gas and dust. About 85% of stars form double or more stars, and more than 50% of stars, such as the Sun, form a dual pattern.

The solar system was now supposed to be a "geek" of the universe of stars, with only one in the sky, but it was supposed that they formed a dual system with other stars.

The fact that the sun pushed the twin stars and buried them in the innumerable stars of our galaxy, and that they could not find them, was a twin or a fraternal star.

Although some of the solar sibling candidates have been revealed so far, Dr Adybeckan's research team has found more candidates based on extensive astronomical data collected by the Gaia satellites of the European Space Agency.

This star is the "main G-type sequence", like the sun, slightly larger than the sun, with similar surface temperature and brightness. In addition, the composition and composition of the elements forming the celestial bodies are almost the same, and the age of generations is about 4.5 billion years ago.

It is closer to the sun than the star type "HD162826", which was announced by the sun brother in 2014. The temperature of the star star type F reaches 8000 K (absolute temperature), but the G type differs by 6000 K.

"Because there is not much information about the past of the Sun, the study of the Sun Brotherhood can help us understand where the sun and the environment in which it came from," said Dr. Adybeckan.

It is also recognized as a shortcut to finding extraterrestrial life, because the solar system is unique in understanding the existence of life in the universe.

It is also possible that living entities evolve in twin stars or stars of siblings similar to the Sun.

Dr Adybeckan pointed out in his theoretical calculations that during the late bombardment, which took place about 3.8 billion years ago, when there were frequent collisions with the consequences, "the possibility of living organisms spreading from other planets or foreign planetary systems on Earth is not it is negligible. "He said.

In addition, HD186302 added: "If you have a rocky planet on which life can live, and this planet is contaminated with earthly life forms, we will have a dream of 2.0 that will lead to the Sun 2.0."

Researchers have found that they focus on observing whether there is a planet around HD162826 as the first step to fulfilling this dream.
