How are young stars formed?
Stars as it turns out are formed as well as the planet, scientists have confirmed their conclusions on the example of the formation of the recently observed object MM 1a. The star originates from matter in the form of a disk, just like planets. A unique photo of a young star was recently obtained. Scientists watched the big star and on the occasion in its orbit saw a mysterious satellite, a young star that stole matter from the mother object. Later, astronomers have divided the stars and have figured out who and where takes the substance. The stars separated from each other for some distance, but formed in the same way as the stars are formed from the protoplanetary disk.
In the center of the entire star performance is a large star surrounded by a large protoplanetary disk. This disk consists of dust and gas. Then scientists explored before to find in this nascent star. All would be a full-time, studied a little drive and all of a sudden.. Object MM 1b was found, it was found on the outer edge of the protoplanetary disk. If the star is not large and the size of our Sun, then the protoplanetary disk is not as large as one might imagine. From such a disk as a result of fragmentation there are planets of different types. But in the case when a star is many times larger than the Sun and it has a disk of protoplanetary matter is simply huge, then the disk itself can collapse and shrink into another star. That is why there are many times more binary systems than ordinary single stars.
Scientists based on the known technology of counting were able to calculate the mass of each star. In addition, they were able to look closely through the telescope of the radio Observatory Atacama Large Millimetre/submillimetre Array (ALMA), so that the discovery is confirmed from different sources. The main star in the binary system MM 1a is 40 times the mass of the Sun, but the star originated in the disk of dust and gases barely gets to half the mass of the Sun. Scientists believe that this system is not very stable. Perhaps so, but time will pass and a small star being quite active will grow to five masses of the Sun for example, and then the system will be very stable, but it will not be soon...
