The first stars of the universe can be far smaller than our view, research indicators – possibly explains why it is so difficult to find evidence in their existence.
According to new research, the early generation of stars had a difficult history. These stars came into a violent environment: a huge gas flogged with a supersonic speed riot five times faster at the speed of sound inside the cloud (as measured in the Earth’s environment).
An imitation of the new research also shows that the gases are cluster in bales and collision that raises the upcoming star berth. The cloud was broken, causing pieces from which the stars were exposed. A gas cloud eventually settled in the right situation for the formation of our sun’s widespread stars-which was considered earlier in our early universe, was much smaller than researchers of large-scale researchers of 100 molds.
These results have indicated that the first supergunant stars in history can be in brilliant networks – as was thought earlier, not in excellent isolation.
“With the presence of supersonic riots, the cloud is scattered in more than one small flag, which is instead of forming a few larger stars.” Jong Chen ofAcademia Sanika Institute of astronomy and astronomical physics in Taiwan told Life Science via email.
This glimpse of our early history is very important to learn about our galaxy as well as our solar system.
“These first stars played an important role in the formation of preliminary galaxies, which eventually developed in systems like our own sky.” With this new model, he added, adding that fresh observations can bring more research, in which the structure of the star berth and galaxy can be studied using both the computer model and the powerful of NASA.

Imitation of the universe
Researchers used this to create their fresh understanding about the early stars Gizmo simulation codeWhich is used to study the astronomical phenomena from black holls to magnetic fields, and a project called a project that has been shown earlier Correct the Galaxy formation correctly. Their purpose was to study our cosmic conditions a few hundred million years ago, 13.8 billion years ago.

Given the sheer scale of the universe, the counterfeit is focused on the same area: a dense structure, which is 10 million times more than our sun’s widespread, called Manihulo of a dark matter.

However, we can evaluate the presence of dark matter through its gravity effect on other things.)
Researchers examined how the gas particles are growing in small areas of the space inside the hala, measures about three light years in each region. The images showed that the dark material .In the Munihulo attracts the gas through gravity, and by doing so, the supersonic speed creates both cloud cloud clumping. So the violence was part of the initial stars.
This traumatic environment created another side effect: there were far greater, the early stars we thought before. The previous research said that we could have more than 100 solar people’s early stars. Finally, these old stars burst as supernovas, and surpassed the remains behind them, which would have joined the new stars as soon as they grow.
However, new stars do not show any chemical signatures of the giant already – showing that the first generation of many stars can be really rare.
Chen’s team has not yet been done. Now they are using the dark matter to see how the supersonic turmoil in the early universe usually worked, especially when the first stars emerged 13 billion years ago, called the “Kinati Dawn”.
“This article is part of an attempt to cooperate with the first of the first to understand the cosmic rising dawn through the investigation of the formation and evolution of the stars,” Chen said Chen said.
He added that the next set of imitation may also include a magnetic field. We can see in galaxies today that the supersonic promotes the turbulent magnetic fields and affects the structure of the star. It can be very well that magnetism was just as important for the formation of a star in the early universe.
Chen’s team published its results in the journal on July 30 The letters of the astronomical journal.
