The dual solar system generates close to the ground

A group of astronomers from the Japanese Astronomical Observatory led by Tomoyoko Kudo said that Earth-like planets form after the birth of the newly born "DM Taurus" star, similar to the sun.

According to Astrophysical Journal Letters, which published the findings of the scientific team, the star "DM Taurus" lies 470 light-years away from the Earth, looks like the sun and measures half of its mass, to the age of 3 to 5 million years, while the sun is estimated at about five billion years.

For a long time, astronomers have observed a dust disk around the star, sign of the birth of a new planet. However, different scientific groups have not reached a unified agreement on a shelf.

"Previous studies have generated two disk models around the DM Taurus, some studies have shown that the disk radius is similar to that of solar system asteroids, while the other indicates that it is similar to Neptune's orbit and our follow-up with the help of the ALMA telescope gave a precise answer.And it turned out that both views are true because the star rings twice.

The new star has two rings

Astronomers followed the radio waves emitted by dust and carbon dioxide, allowing them to determine the radius of the inner ring, equivalent to four astronomical units (astronomical unit equal to the distance between the Earth and the Sun). The outer ring, with a radius of 20 astronomical units. He also discovered a dust disk far from the star, separated by the slit of the outer ring.

Astronomers focus their attention on the inner ring which, according to the theory of the emergence of the solar system, must generate rocky planets. But nothing indicates where the process of creating the worlds happened.

The outer ring, where astronomers have discovered a bright spot, refers to the location of the dust concentration. It is expected that it generates a gas giant similar to Neptune or Uranus.
