What do young stars tell us about the birth of our solar system?

What star at the center of our solar system needs billions of years to mature and ultimately provide the energy that gives us life here on Earth, but a long time ago our sun was just a little star growing , and here we say what the sun looked like when it was very small? This has always been a mystery that, if solved, could tell us about the formation of our solar system, which is so named because sol is the Latin word for the sun, and other star systems made up of planets and of cosmic bodies orbiting stars.

the site said “physical “We have discovered thousands of planets in other star systems in our galaxy, but where do all these planets come from, where does Earth come from? That’s what really motivates me,” said Catherine Espilat, author principal of the Boston University article. Associate Professor of Astronomy at the College of Arts and Sciences. .

And presented a new research paper published in Nature through Espaillat He and his collaborators provide new clues to the forces at play when our sun was in its infancy, and for the first time discovered a unique shape point on a young star that reveals new information about the growth of young stars..

Espilat explains that when a young star forms, it devours the particles of dust and gas that revolve around it in what is called the protoplanetary disk, and the particles collide with the star’s surface in a process called accretion.

And“It’s the same process that the sun went through ”, says Espilat.

The disks of the protoplanets have been found in magnetic molecular clouds, which astronomers know throughout the universe as fertile ground for the formation of new stars. Very hot and dense hot spots form at focal points of the process. accretion..

Looking at a young star about 450 million light years from Earth, observations by Espilat and his team for the first time confirm the accuracy of accretion models developed by astronomers to predict point formation hot. developing stars, and now observable data supports these calculations.

The Boston University team, including graduate student John Windeburn and postdoctoral researcher Thanwoth Thanathibodi, also closely studied a young star named GM Au Fall into a cloud Taurus-Auriga It is currently impossible to image the surface of a star this far away, says Espilat, but other types of images are possible since different parts of the star’s surface emit light of different lengths. wave. The team spent a month taking daily snapshots of wavelengths of light emitted from a surface GM Au , and collect datasets from x-rays, UV rays (UV), infrared and visible. To take a look GM Au They relied on the “eyes” of NASA’s Hubble Space Telescope and the transit satellite for the recognition of exoplanets (TESS) Fast The observatory’s global network of telescopes The hills.
