Телескоп ALMA зафиксировал в созвездии Волка рождение звезды и планетSimultaneous formation of the star HD 142527, located in the constellation of the Wolf and the surrounding planets recorded ALMA telescope that helped scientists later to find out how matter protoplanetary disk is moved to the star, despite the great distance between them, reported in an article published in the current issue of the journal Nature.

Planets and stars, according to scientists, are born as a result of gravitational collapse in the densest parts of dust nebulae. Flashing, the "embryo" of light that passes close to it part of the protoplanetary disk, removing from the borders of a future star systems remains of gas and dust. However, the weight of the star continues to rise, this process and is, in fact, a kind of a scientific mystery.

The team of astrophysicists led by Simon Casassus from the University of Chile in Santiago have found to this question the answer, having studied in detail the young star HD 142527, which is located at a distance of 450 light-years from Earth in the constellation Lupus under still unfinished ALMA telescope.

Casassus and his colleagues found that a gap exists between the young star and the protoplanetary disk, filled with rarefied gas layer. This is evidenced by the presence of the molecules of carbon monoxide (CO), their radiation was captured by the telescope.

The scientists also found inside the disk of a spiral flows of gas, which unambiguously points to the existence of the protoplanetary bodies or these planets. The type of the flows of matter suggests that the planet, increasing weight, tighten it on himself.

This process, according to the scientists, allow the star to grow further and at the same time prevents destroy the protoplanetary disk with radiation. According to calculations by the authors, supplied future planets volume of gas is enough to explain the current pace of light.

Casassus and his colleagues, revealing the secrets of the birth of star systems, decided to check when using a computer model that would have happened with a protoplanetary disk in the absence of the gas streams. HD 142527 in this case would destroy the disk during the year, resulting in the growth of the system would be stopped.

This gives reason to speak about the extreme importance of this process for the formation of full-fledged planets and stars. In the spring of 2013, the authors plan to conduct another series of observations, then, as expected, the design of the ALMA will be completed. More accurate data will help scientists to "weigh" and planets, and the star system HD 142527.
