A star is being born in no time: the scientists are redefining the process of planet birth

A star is being born in no time

The scientists from the Netherlands have found an evidence for the new calculations to determine the period of birth of new stars and planets. By the cosmic standards, that event takes place literally in the blink of an eye. The researchers were able to explain the new evidence for that amazing cosmic phenomenon based on the results obtained using the combined power of two telescopes: the powerful Atacama Large Millimeter radio system and one of the world's leading observatories Very Large Array.

A study of astronomers has demonstrated the features of space. It turns out that very young disks, that's age is from 0.1 to 0.5 million years, have more than enough parts for assembling the planetary system.


For many years, the scientists have been puzzled by the issues related to the period of birth of new planets. And only today they managed to find out a plausible solution. In recent years, the astronomers have weighed young planetary disks throughout the Milky Way. To do that, they needed the help of the ALMA system.

After examining the discs, which are 1-3 million years old, the astronomers came to the conclusion that they all show a lack of dust in these mature discs. And that drawback does not allow them to create at least one gas planet, such as the Jupiter. That fact confirms that the age disks in our solar system are not able to form a giant planet.

Lukas Tikhonets, a graduate student at the Leiden Observatory, believes that he and his colleagues managed to find the right solution. It consists in the fact that one should consider younger disks, and not look for the missing mass of failed new planetary formations.


He and his colleagues used images of the Perseus molecular cloud - one of the giant spheres of the star formation, located at a distance of 1000 light-years. The astronomers suggest that the age of the stellar systems ranges from 100 thousand to 500 thousand years. If we assume that the Sun is 45 “human” years (4.5 billion space years), then the protostars are equivalent to an age of less than two days.

Young discs are equipped with dust grains, and the mass contained in these solids is more than enough to create giant planets. The meaning of that discovery can change the direction of the study of young discs and the star formation process.
