Fellow of the National Council for Scientific and Technological Research (Conice), Which is part of the city’s astronomical institute When paying, Was able to measure the mass of The hottest giant star in the galaxy, A very important piece of information to understand about its development and evolution.
Thanks to images obtained at the Los Campanas Laboratory in the mountains of the Atacama Desert in Chile, a team of experts, including an Argentine scientist, was able to list and classify the named star. HM1 8.
As explained from Connaught, knowing Time – The object that holds an object – The size of a star is essential in this field of research. From this information, we can derive the evolution that matter contains, “that is, how it is born, what stages it goes through, how long it lives, and how it dies.”
“The Institute of Astrophysica de la Plata (IALP, CONICET-UNLP)’s, the largest and hottest star ever recorded in our galaxy, has been able to measure mass, the researchers commented.
139 such stars are known in the galaxy
There are a total of about 100 billion stars in the Milky Way, only a few thousand of them Massive –Stars that weigh 8 times or more than the Sun at birth. “Of the latter, only 138 are known” and HM1 8, which was studied by this research team, is now listed as 139.
HM1 8 is 9 thousand light years away from Earth. Its mass is 34 times that of the Sun and its diameter is 10 times greater than that of the Sun. It also has a 7 times higher surface temperature.
Another interesting fact about the celestial body studied is that the luminosity is “greater than the energy emitted by the central star of the solar system: it shines 250 thousand times brighter”.
Observations show that it is about 2 million years old, in terms of its age. That is, taking into account that these massive objects last less than 10 million years, its lifespan, more or less in the middle of its life, is several thousand years, compared to the smaller ones. Millions of years.
We star dust
The Massive stars Only they can create all the chemical elements of the timeline throughout their evolution. So it is important to know more about its development.
“Initially, when the universe appeared, there were only two gases: Hydrogen and helium. The remaining elements such as calcium, carbon, oxygen and many more were formed over time Stars, Every time one of them is destroyed you have to shoot in space “, maps by Gabriel Ferrero, an IALP astronomer and research author.
“Through this process, the atoms of our body were created, so ‘We star dust” He added.
However, not all stars are capable of producing these elements, but the largest of them is HM1 8, which is now classified as “the largest and hottest star available for accurate measurements across the Milky Way”.
