La largest star in the Milky Way Also known as a hypergiant, it is an extremely large and massive star, even larger than a supergiant. Its mass can be up to 100 times the mass of our sun, close to the theoretical maximum limit, which states that the total mass of a star cannot exceed 120 solar masses. For more information on stars in general, you can visit our article on characteristics of stars.
In this sense, this limit in mass is lumped in with the Eddington glow, whereby more massive stars simply cannot be in proportion by overcoming the internal effulgence constraint to the gravitational power: they would originate so much energy that they would get rid of the mass in abundance of the 120 solar masses.
Even so, some hyper giants pretend to have more than 100 solar masses and, even, to have initially had between 200 and 250 solar masses, contrary to what is announced by current hypotheses about the creation of the cosmos and space progress.
In relation to the above, it is considered that the largest star in the Milky Way or a hypergiant they are the brightest stars there are; thousands and millions of times brighter than the star king, with surface temperatures between 3.500 K and 35.000 K. They have about an average life of only 1 to 3 million years before becoming what what is supernova or, in highly anomalous cases, hypernovae.
The data
It has been assumed that a hypergiant that will be baptized as a supernova or hypernova and will also leave a black hole as a remnant in its area. For more information, you can read about black holes.
What is known about the largest star in the Milky Way?
Very little is known about hypergiants, as they are considerably anomalous. Until recently only 7 hypergiants were frequented in the Milky Way. At the same time, they can vary in hue: blue basically shows that the star is very hot (on its surface), while red shows that it is cooler; there are also yellow ones, but the imbalance produced by the restrained temperatures and high obligues in their interior make them more anomalous than the other contingencies.

The curious thing about the largest star in the Milky Way
It is attractive to perceive that the hypergiants most radiant yellow and red are of a bolometric dimension of about -9,5 - which is equivalent to a brightness 500.000 times that of the Sun - and none with a higher brightness are known. The causes by which this occurs are still unknown. If you are interested in this topic, you could read more about Shooting Stars.
haunted hypergiants
If it is true that mention is made of the star largest in the Milky Way, however it is important to classify those that are larger in relation to this characteristic.
Versatile shimmering blues
blue versatile stars The resplendent or Wolf Rayet's Star are the most massive, magnificent and radiant, they are classified as hypergiants. Precisely, they are the most splendid stars that are frequented:
1.P Cygni
These they are very unusual stars and form the most radiant stars in the galaxy. Their flares are caused as the star approaches the Eddington limit, causing the radiation pressure to force its mantles outwards more violently. This exploration of stars can be related to the star nomenclature.
In this order of ideas, P Cygni is surrounded by a graceful galaxy that it has been founded during the last 900 years by the expulsions of the star; In the same way, there are debris from previous emissions that took place 2.400 and 20.000 years ago. The star continues to shed mass at an astonishing rate, 300 million times greater than the Sun's loss of storage from the solar wind.
The use of such a formidable object is to a certain extent insecure; it can either explode as a radiant supernova or it can end up as a hypernova, where the focus collapses towards a black hole. To learn more about this topic, you can read about the types of stars.
In the same way, it has been insinuated that the aforementioned emissions may have been produced by the transfer of mass to a dubious space companion in the same way as spectral class B, which would have an estimated mass between 3 and 6 times that of the Sun. towards the aggregate it would release gravitational momentum, a portion of which would be changed into an enhancement of clarity. Said companion would use about 7 years to perfect an orbit, this being very unusual.
2.S Doradus
S Doradus is a versatile star in the Antarctic zone of Dorado, model of a genus of variables that bear his nickname, Versatile S Doradus or Resplendent Blue Versatile. It does not concern our galaxy, the Milky Way, but the accessible cluster NGC 1910 in the Large Magellanic Cloud and is about 180.000 light-years from the solar system.
With a hardcore dimension that can go as low as -10 and a clarity of over 1 million suns, S Doradus It is a hypergiant star and one of the brightest that can be seen.. However, the great distance that separates us from it makes it incorporeal at first glance. Its assumed dimension varies between +8,6 and +11,7, with slow and long-lasting glow differentiations, scattered by chance bursts. Its surface temperature is minimal compared to other splendid blue variables, but its axis is greater.
His countenance is analogous to that of the star P Cygni, changeable from the same example. These stars are very strong, at least 60 times more than the star king, and their life cannot exceed a few million years. Cultures from the year 1999 state that now the spectrum of this star is analogous to that of a supergiant star of spectral class F, something that had not been noticed in the previous 50 years, despite profuse events the star had the same glow. The origin of this permutation is excluded.
3. Eta Carinae
Eta Carinae is a hypermassive blue glowing variable class star., located in the Keel region, approximately 7500 light-years from the solar system. Its mass fluctuates between 100 and 150 times that of the Sun, making it one of the most massive stars frequented in our nebula.
In the same way, it has an excellent clarity, about four million times that of the Sun; Due to the large amount of dust surrounding it, Eta Carinae scatters 99% of its light in the infrared part of the spectrum, making it one of the brightest stars in the sky at wavelengths between 10 and 20 µm. If you want to know more about starlight, you can consult the article on the starry Night.
Eta Carinae is one of the parts of the cosmos that until now has been considered very young, with an age of between two and three million years, and is located in NGC 3372, Similarly cited the Great Carina Nebula or simply Carina Nebula. The star is surrounded by a galaxy presented as the Homunculus Nebula. Given its large stock, Eta Carinae is deeply hesitant and exposed to ejection forces of a cosmic component.
Finally, if it is a question of the largest star in the Milky WayEta Carinae is likely to end its life in a hypernova explosion within a few thousand years. Some observers speculate that this will happen within a much shorter time interval, but there is much uncertainty about this. the progress of super massive stars it is very difficult to form numerically.
