Why is the information of an alien star in the Big Dipper unique?

Because the metal content of J1124+4535 is quite low, but the content of some elements is unexpectedly high. We all know that the vastness of the universe is beyond the reach of human imagination. For humans, the earth is already a behemoth; But when the earth is put into the universe, it is still just a "drop in the ocean".

There are also many strange phenomena in the universe that are difficult to explain in our existing physical theories. For example, we recently observed an "alien star" in the Big Dipper, which has properties that are diametrically opposed to what we have learned so far. Where does this begin?

First of all, the origin of J1124 + 4535 is different from that of ordinary stars. Friends who are familiar with physics knowledge and often read various popular science books may know that the origin of stars is actually very simple, that is, a process of "the old does not go to the new and does not come". When a star enters the death phase when it runs out of fuel, it will eject a large amount of energy, causing the so-called "cosmic fireworks" phenomenon; And in the cosmic fireworks, new stars are created due to large-scale bursts of energy.

But thisAlien stars, as the name suggests, break all common sense. According to the current scientific model built by NASA, it is speculated that it was not born from "cosmic fireworks", but is likely to be the result of a collision between a previous "dwarf galaxy" and our Milky Way.

Since it is a so-called collision product, the surface information of this star will be even more beyond our imagination. According to the current detections, we have obtained a lot of shocking information from this star: we all know that although many conditions are different, stars tend to have similar elemental ratios, and there will be no "roller coaster" of dramatic changes.

But on this star, the metallic elements that are ubiquitous in other stars are largely extinct on J1124+4535; But heavy metal elements, J1124 + 4535 can be said to be "everything".

To sum up, because the metal elements of J1124 + 4535 are too lacking, heavy metals are common, so the element ratio is very peculiar.

Alien star, a noun with its own attraction, as the name suggests, is a special star. Scientists have simulated the formation of spiral galaxies in computers, with many small galaxies piling up to form part of the structure of a halo. Even after the merger of galaxies occurs, there will still be individual stars that retain the chemical traces of their original galaxies.

According to the clues provided by the star's chemical fingerprint, there is a special star in the Big Dipper, which is like an intergalactic alien existence.

According to the new study, this particular star has unusual chemical signatures, and it also has a chemical identity that is different from that of all known stars in the Milky Way, but has many similarities with stars in nearby dwarf galaxies. The star, named J1124 + 4535, scientists suspect that its strange origin should be a dwarf galaxy that collided with the Milky Way long ago. Based on this reasoning, it can be concluded that the time when the star was trapped near us should be when the dwarf galaxy fell apart.

The elemental ratio is a unique star.

In 2015, China's large Sky Multi-Target Fiber Optic Spectroscopy Telescope (LAMOST) first discovered the star in the constellation Ursa Major, and Japan's Subaru Telescope also took higher-resolution images in 2017. Through the collected spectral readings of the star, it was found that the star has relatively low levels of magnesium and other metals, but its heavy metal element europium content far exceeds the expectations of scientists.

Scientists say that if compared to other stars in the Milky Way, its elemental ratio is also unique. These elements in the star also reflect the composition of the dust and gas clouds formed by the star. In general, the material composition of neighboring stars is generally the same, so they often have similar chemical characteristics.

But when a star is different from the other stars in the group, scientists need to look elsewhere for where it might have been born.

Except for the human factor, all are unique.

Isn't everything in the world unique?

I think this matter is a secret for the time being, and it will come out after a while.

Nothing is special except for the man-made.

Time is the best interpreter, so let's be patient and wait until the answer is revealed.

I don't think this question will be answered for the time being, and it needs to be observed for a long time.

This is because of what is necessary for life now.

All are unique.

Because the cosmic space in which this star is located is relatively special, this makes its elemental ratio mutate.

I think it's probably because humans still don't know enough about the planet, which leads to the wrong information in the exploration. Of course, it is also possible that the composition of matter on that planet is completely different from our periodic table.
