Astronomers have proposed a new theory that attempts to explain the existence of particular chemical elements in ancient star clusters known as globular clusters.
Globular clusters are ancient compact clusters of hundreds of thousands of stars closely packed by gravity. formed 11-13 billion years ago, just a few cosmic moments after the Big Bang .
About 150 of these groups were spotted sitting in the outer regions of the Milky Way, Tech Times reported on Friday
The researchers wanted to know why the stars found in these clusters have different chemical elements from those found in open clusters.
Aside from the significantly higher amounts of helium and hydrogen, the globular stars clusters also have a higher concentration of heavy elements than other stars such as the Sun.
This is often observed in older stars, such as those found in globular clusters, but scientists I have not yet known what caused this particular relationship. elements.
The secrets of the universe are waiting to be unraveled [19659009] The elements and their particular relationship could not have been produced even within the stars. Researchers believe that it takes a temperature 10 times higher than that of stars during their training.
A team of astronomers believes that it can be seen in supermbadive stars, having a mbad that is tens of thousands of times more
The study, published in the journal Monthly Notices of the Royal Astronomical Society advance the idea that supermbadive stars could have appeared at the same time that globular clusters were beginning to
During the early years of the Universe, clusters Globular were filled with dense hot gas that would cool down later to form the large number of stars in the cluster.
As the stars accumulated more matter, the researchers believe that they have grown tall and so close to each other that some of them would collide to form a supermbadive star.
The supermbadive star would then reach temperatures high enough to be able to produce heavy elements and other chemicals. We can now observe the stars in globular clusters.
"What is really new in our model is that the formation of supermbadive stars and globular clusters is intimately linked," said Mark Gieles, principal investigator at the University of Surrey.
"And this new mechanism is the first model that can train enough material to pollute the cluster, and with the correct abundance of different elements," adds Gieles.
