The giant star in the Milky Way is slowly dying out

VY Canis Majoris

Scientists are developing a detailed model of this red hypergiant that is considered to be the largest star in the Milky Way.

Examples of three-dimensional celestial bodies can be ridiculously difficult. They can emerge from dark holes where light does not escape the growth of the universe and everything in between. Not all items have received the impression of making a full color, but we can add another very complex color to our list.

Astronomers at the University of Arizona have developed a model for VY Canis Majoris, a red hypergiant that could be the largest star in the Milky Way. And he is using that example to predict how he will die.

How red hypergiants die has been a contentious issue recently. At first, astronomers thought they had exploded in a supernova, like many other stars. However, recent data show a significant shortage of supernovae compared to the number that would be expected if red hypergiants exploded in this way.

The idea that is circulating now is that it is very possible falling into a black hole, something that is more difficult to see directly than supernova. It is not yet clear which of the elements in the star can turn into black holes, and to be sure, it helps to have a pattern.

Here is the UA team. He chose VY Canis Majoris as the best representative of the red hypergiants who were interested in learning more. The star is large, pregnant 10,000 and 15,000 Astronomical Units (height from Earth to Sun) in size. And it is just 3009 light years away from the Earth right now. This makes VY Canis Majoris, who lives south of the Canis Major star constellation, a favorite for viewers.

Its size and proximity to the Solar System make it ideal for inspection. With good monitoring data, astronomers can see high complexity of the stars.

One of the most important factors in star death is mass loss. Usually, this occurs when air and dust are uniformly emitted from the star photosphere. However, in VY Canis Majoris, there are some major similarities and coronal arcs of the sunbut multiply twice.

The researchers spent time on the ALMA telescope to capture radios from objects released into the atmosphere as part of the explosion. The story allows them to realize the speed at which it is moving and to do this, they had to line up all 48 ALMA plates and collect. more than a terabyte of data having accurate knowledge.

He is processing some of the data. However, they already have enough to present their findings to the American Astronomical Society. When he has more, he can make a better example and, in the future, will predict what will happen after the death of VY Canis Majoris.
