The telescope observes the triplets star in the universe

The telescope has just recorded the development of a multi-star system in the universe with two young stars orbiting around the central star.

A team of researchers published the discovery of the formation of two young stars in a disk of moving gas around an older star than in the October 26 issue of Nature, according to Nature World News.

The new multi-star system, called L1448 IRS3B, is located in the constellation of Anh Tien, 750 light-years from Earth. The team estimates that this system is less than 150,000 years old, the farthest star only about 10,000-20,000 years old.

They use the Atacama Large Millimeter / submillimeter Array telescope (ALMA) and data from the Very Large Array (VLA) radio telescope in Mexico to calculate the distance between stars.

The young inner star orbits around the oldest star in the center from a distance of 61 times the distance from the Earth to the Sun. Meanwhile, the star is outside the same way as the central star nearly 183 times the distance between the Earth and the Sun.

All three stars are surrounded by a physical disk forming a spiral structure. This structure shows the instability of the disk surrounding the stars.

Thanks to the discovery of L1448 IRS3B, astronomers now have direct observational evidence of splitting in disks to create young multi-star systems from the early stages of their development.

"This new study reinforces the hypothesis that there are two mechanisms for forming a multi-star system, including the separation of the disk next to the star as in this case and the second is the splitting of the cluster. gas clouds and dust revolving around the star is forming , " said John Tobin, University of Oklahoma, Netherlands, the study's lead author.
