Through thick clouds of gas and dust, scientists were able to see the bursts of radiation that young stars emit as they gain mass.

Young stars in the Orion Nebula release bright bursts of radiation as they actively absorb matter around them, to calculate the required size of an “adult” star, writes Space.

American astronomers studied archival data from the now retired Spitzer space telescope and found frequent outbursts of radiation from newborn stars (there are still called protostars) in our nearest star-forming region in the Orion Nebula.

According to scientists, these emissions of radiation occur at a very early stage in the development of stars, when they reach an age of 100,000 years. And these outbursts, which are a sign of the gas and dust around the star being swallowed up during mass gain, appear every 400 years. That is, it is very often by cosmic standards.

According to Tom Megit from the University of Toledo, Ohio, USA, the new discovery will help to better understand the processes that occur with stars in the first years of their life, including learn more about how stars can gain mass quickly.

Indeed, until now, scientists have too little information about what happens at the initial stage of the evolution of young stars, and this is due to the fact that they are hidden in a cloud of cold molecular gas and dust from which they appeared. Thanks to observations by the Spitzer Space Telescope, scientists have been able to look inside these clouds and see the bright flashes of light that stars 100,000 years old release.

Astronomers studied archival data on 92 known protostars and found previously unknown bursts of radiation, and also found that they repeat every 400 years. According to scientists, such a frequency of radiation is much higher than the flares that older protostars release.

Astronomers have come to the conclusion that young stars release these radiation fluxes continuously for 15 years. Also, the new study helped scientists determine that during the period when a star develops during the first 100 thousand years, it accumulates about half or even more of its final mass.

According to Megit, young stars, by cosmic standards, gain mass too quickly and increase in size just at the very initial stage of their evolution. Scientists also believe that such bursts of radiation can affect disks of matter in which planets are born. Also, this process can be influenced by the very fact of how the mass of a young star increases.

“We believe that 4.6 billion years ago, before the Earth appeared, perhaps our Sun also produced such bursts of radiation. That is, the Sun was the same “burping after dinner” star. Observing the formation of these young stars allows us to imagine what happened at the very early stage of the formation of the solar system, “says Megith.

< em>Focus already wrote that astronomers found strange “glitches” on the stars, but there are several explanations for these failures in their work.

Focus also wrote that a few months ago the Webb Space Telescope took amazing new images of the Orion Nebula.
