The Sun, the star at the center of our system, has been developing for billions of years and is beginning to provide us with the energy we need to live. But early in his life, he was still as “baby” as any star going through a similar life cycle, writes The Gate Phys.
but What did the sun actually look like when she was still young? This is a question that has not been answered for a long time. If we can find them, we can learn a lot about developing the system we live in today.
“So far, we’ve discovered thousands of planets in other solar systems across our galaxy. But where did these planets come from? How did Earth originate? These were the questions that kept me awake,” says the new study’s author, Catherine Espilat.
Thanks to her new work, we gained a better view of the forces in the system at a time when our Sun was very young. Astronomers managed to discover a young star, marked by one specific point, which can teach us a lot about this period of the star’s life.
When a young star forms, Absorbs dust and gas particles, which are located around it, in the protoplanetary disk. These particles collide with the surface of the star through a process called accretion.
“It’s the same process that our sun went through,” Espilat explains.
Protoplanetary disks are located within magnetic molecular clouds. These are also known as new star hatcheries. We have long assumed that the protoplanetary disks are connected to a star by a magnetic field, and that the particles follow the lines of this field back to the star. Then, these particles collide with the surface of the star and form a kind of patch that is very hot and dense. This is the center of the accumulation process.
The observation of a young star 450 million light-years away confirmed these theories. For the first time, astronomers had the opportunity to check their models, which turned out to be correct. This is star GM Aur, who cannot be photographed directly due to his distance. However, a team of scientists has found a way to create an image using Different wavelengths of radiationThat star is flying into space.
GM Aur has been found to complete a rotation on its axis in about a week. During this period, its brightness fluctuates depending on whether the hot spots are facing us or not. When scientists first looked at the data they had, remained listed.
“We found an inconsistency in the data within about a day. We went through it over and over to make sure we didn’t do anything wrong. It turns out that in the spot where the material is falling from the disk, there’s another spot, and it’s hotter,” Espilat says.
This spot is not a complete circle, but it is similar to the shape of an arc. But part of it is hotter than the other. The team learned that these spots are a fingerprint of the magnetic field on the star’s surface. a J the sun She had similar points in her youth.
