99.8% of the mass of the solar system is occupied by the Sun, as the only star, the Sun firmly holds the dominant position in the entire star system.
In the Milky Way, single-star systems like our Sun are rare.
According to the statistics, 85% of stars in the Milky Way are multi-star systems such as doubles and triplesif the stars have more mass, this ratio will increase even more, but recently astronomers have discovered that this rule doesn’t seem to apply near the center of the Milky Way. .
Devin Chu of the University of California, Los Angeles (UCLA) led his research team analyzing stars near the black hole at the center of the Milky Way. They used the Keck Observatory in Hawaii to spend 10 years tracking 28 stars orbiting the supermassive black hole.

Double optical star
in astronomy, optical binary This is the case when two stars appear close to each other when viewed from Earth. There are two types of optical binary: the visual binary – which is a true binary system, and the apparent optical binary – two stars that appear close, but are actually very far away.
The black hole at the center of the Milky Way is also known as Sagittarius A*, about 44 million km in diameter, 4.3 million times the mass of the Sun, is a typical supermassive black hole. The environment close to a black hole is very complex and chaotic, its gravity will strongly interfere with celestial bodies, even swallow stars. Therefore, scientists generally believe that it is very difficult for new stars to appear near black holes.
However, of the stars the researchers tracked, 16 are relatively young, born just over 6 million years ago, and all of them are very massive, with masses typically 10 times greater than the mass. of the Sun.
This raises many doubts. The reason is that it is difficult to create new stars near black holes, and these young stars do not have enough time to migrate here after forming elsewhere. On the other hand, scientists analyzed the spectra of these stars and found that they were all unique stars.

The highest probability for stars to form near the Sagittarius A* black hole is 47%.
The highest probability for stars to form a binary system near the Sagittarius A* black hole is 47%.
As we mentioned above, multi-star systems are the normal and common state of the Milky Way, especially for massive stars, the probability of forming binary systems or even a three-star system is relatively high.
The researchers sorted through the observations and concluded that the highest probability for stars to form a binary system near the black hole at the center of the Milky Way is around 47%. All seem to be linked to the supermassive black hole Gagittarius A*.
The researchers suggested two possibilities, the first one is the gravity of the black hole that broke the original binary system, and the remaining star was thrown under the gravitational force of the black hole. This is quite achievable in all situations, from theory to practice. Scientists have discovered many stars that “run away” from the Milky Way at high speed, and they often fly out of the Milky Way at speeds of over 1.6 million km/h.

The gravity of a black hole is strong enough to break up binary star systems
The gravity of a black hole is strong enough to shatter binary star systems.
Another possibility are stars that are actually much older than we see. A black hole’s gravity is strong enough to shatter binary star systems, causing them to collide and merge. It could also explain why such young stars appear in such a hostile environment.
In a way, these stars can be considered lucky stars. Because running around a black hole is extremely dangerous, because in such a situation many celestial bodies are likely to be shredded and swallowed. For objects close to a black hole, the scariest thing is the tidal force of the black hole.

The gravitational pull on the side of the star near the black hole is much stronger than on the other side
The gravitational pull on the side of the star near the black hole is much stronger than on the other side.
We all know that the gravitational force of two objects is related to the distance between them. The gravitational force on the side of the star near the black hole is much stronger than the other side, when the gravitational difference between the two sides is greater than the gravity of the star itself, the star will will stretch in its own direction of motion It’s like noodles.
From a sphere to an ellipse, and finally a long rod. The next thing the star has to face is the fate of decay, and the torn star will rapidly approach the black hole until it is engulfed.

A black hole with a mass of 100 billion suns would evaporate in 2×10^100 years.
A black hole with a mass of 100 billion suns would evaporate in 2×10^100 years.
Although a black hole seems so terrifying that nothing can resist it, it will die over time.
As the black hole devours matter, it also emits matter outward. In other words, not only will it expand endlessly, but it will also burn out. Scientists have calculated that a black hole with a mass of 100 billion solar masses will evaporate in 2×10^100 years, and during the evolution of the black hole, if not enough matter is absorbed, the black hole will accelerate the disintegration process.
However, considering the existence of human civilization, we can barely see the end of the black hole. But the study of black holes has become a necessity for humanity, because behind it hide too many mysteries that we ignore.
