The formation of the new luminaries of the protoplanetary disk, the researchers observed for the first time.
It is known that from the protoplanetary disk formed from the stellar gas and dust, planetary systems are born. However, the giant young star, which has produced another star, astronomers observed for the first time.
Scientists from the University of Leeds investigated the protoplanetary disk, rotating in very hot, huge (about the size of 40 suns) and young star MM1a. In it, to their surprise, they found another weak shone MM1b.
“Stars are formed in huge clouds of gas and dust in interstellar space, explains astrophysicist John Or. When these nebulae apart under the influence of gravity, they begin to spin faster, forming a disk around a star center. In disks around stars of low mass like our Sun, the planets formed. In this case the star and the disk are so large that instead of planets, there appeared another star”.
For radiation and luminosity of the star gas scientists have calculated the mass of stars MM1a and MM1b.
The researchers said that a newborn star MM1b are also surrounded by a protoplanetary disk, from which can appear the planet.
These planetary systems have short lives, about a million years until the supermassive companion star will become a supernova and destroy them.
