You know the stars. Even you have seen them. Not only you but also we all can see that in the sky. Do you know what a star is??? I only know that stars are shining in the sky. But actually, what is the appearance of the stars??? what are the components in the stars?? I’ll tell you them definitely. Where can I tell them? It is just here. From the below part of this paragraph. Would you like it??? Then we will start.
What is a star??
This is an object included in the space. That means the outer of our earth. Similar to the human stars also have a birth and an end of their lifetimes. You know about one star very well. That is the sun. That helps us to survive. There is an order to identify these types of stars. I think you are aware of the constellation. Do you know what the purpose of constellation patterns is??
Stars are divided into constellations. You can identify them very easily because of that. Do you know the reason to be the glow that stars??? The reason is thermonuclear fusion. That takes place with the hydrogen and helium. How is that star formed?? I mean the start of life. That is because of the gravitational collapse. That is taking place at the nebula. That nebula is composed of some gases. Those gases are such as helium and hydrogen.
Do you know the star systems?? They are the binary star system and the multi-star system. With the collection of stars, there can make a huge structure. That is the star cluster. Or else that can be a galaxy. Then I would like to move your attention towards the features of the stars.
Special features of the stars
In the beginning, we will see the age of the star.
Not like humans, they have a history of million and billion ages. Many stars have an age of 1 billion to 10 billion years. At least they have an age of 13.8 billion.
Then we will see about the,
As I told above, mainly, there is hydrogen and helium contained in the stars. Approximately 71% contain hydrogen and 27 % helium. Not only these above two gases but also there are some components in the stars. Iron is also contained in the stars.
Except then the above, some stars contain. Usually in such type of stars chromium and the some other. Some other stars with cooler environments. That is through the diatomic and polyatomic molecules.
Then after that, we will discuss the diameter of the,
I think the minimum diameter of the star can be the diameter of the neutron star. The range of diameter is about 20 km – 40km. But some of the stars have a diameter is about 1000 times about the sun. Examples for them such as Betelgeuse. Betelgeuse is a star contained in the Orion constellation.
Finally, I have to tell you about the magnetic field. I have to tell you about that,
The magnetic field generated within the inside the star. But it can be spread outward to the star too. The stars are having high levels of surface activity. That is a result of the magnetic field. The magnetic lines start from the surface of the stars. Then it will end up from outer space.
There are some other factors like mass, temperature, and some other things. We can talk. But now we have to move back to the main topic. We will see some more about them in our future articles.
I think in the above I told you about the Betelgeuse. That is, for example. Today we are here to see the details about Betelgeuse. I have to say some exciting news about Betelgeuse. That is the reason for writing this article.
The new news is, one day, Betelgeuse explodes as a supernova. Because that is a giant star, actually, the giant not only means the size but also it means to age. Do you know the location of the above star?? That is in a famous constellation. Can you imagine?? That is in the Orion constellation. Orion is presenting some special characteristics in these days. But that cannot be detected easily.
I said that this could be seen as a dimming object in the sky these days. According to scientists, this characteristic shows signs of the explosion of the supernovae. Do you know the last supernova?? That is the supernova 1987A. Have you some ideas about that?? That can be known as a satellite. That satellite is situated in our galaxy. That explodes inside the Magellanic galaxy. If I have some more time, I’ll tell you about some more details of the above galaxy.
But I have a question. Does the dimming mean the explosion?? Or else is that show us a potential explosion of the supernova?? I can tell you something definitely. As for the recent discoveries, scientists say that this is not going to explode recently. That will bright than the above. As for example, this will be bright similar to the moon in the full moon.
The brightness of the star is not an irregular action. That can be a frequent action. In earlier times, it bright and fade. Now the amazing thing is that it doesn’t fade. This provides evidence for the supernova. It shows periodic brightness. Sometimes the explosion of a star can happen after many years.
The recent research shows Betelgeuse has about 20 solar masses. That is not definite or accurate. That can be range from 15 to 24 solar mass. Until now, scientists have found out Betelgeuse as the only star that would like to be a Supernova. There is no such thing as a star.
Betelgeuse is a good opportunity for the explosion of the supernova. You can use that opportunity. Then we can see about the main star caused this explosion. Shall we move towards that???
About the Betelgeuse star
In the above, even if I told you that some details about the related star. That is Betelgeuse. That is in the Orion constellation. The evolutionary stage can be described as a red supergiant. Like our sun. This above star classified as the brightest object in the star. Usually, the sun and venus are in the first places on the list. I can tell you the definite place that Betelgeuse occupies. That is the eleven. And the Rigel is the brightest object in the Orion. Because of that, Betelgeuse, it is moved to the second place from the Orion constellation.
The name red giant is a suitable name for you. Because that is red in color. The magnitude of the star is amazing. That is 0.0 and 1.3. Those two are positive values. This is only the star that shows such a magnitude. This is one of many stars that can be seen with our naked eye. And there is another thing about the star. That is only the extrasolar star in the space. And the angular diameter of the above star has to tell definitely. Because that is from about 0.042 to 0.056. The measuring unit is the arc seconds.
This above star is not alone. Because there are somethings in the there, that is the envelope. That is larger about the 250 times of the above star. Do you know in which way that this is making?? I’ll tell you that. The formation is because of the mass loss of the own star. The dimming of the star began recently. I can tell you the exact date. That was in October of 2019.
The name of the above star is not familiar to us. Do we have to find how this was named as?? That is an essential thing. This is a word of the Arabic term. Do you know the meaning?? That means the armpit of the Orion. I agree with that. That shows the correct meaning by Betelgeuse. There is another meaning for that even. That is the hand of the Orion. Yes, I agree with that, even. That Betelgeuse is like a body part of the Orion.
Betelgeuse takes an important place in the history of the red stars. Because that is the first red star, I can not say this is the oldest red star. But this is the detected first red star. There are many special points in the history of the red giants. But I cannot tell them all here. Therefore I only mentioned some significant points of its history. Not only the brightness of the star but also the temperature is varying from the star.
Then we will see about the physical characteristics of the above star because those are very important.
The type of the above star is known as the M1-2-la-ab. The above M letter shows that this belongs to the M spectral class. The first feature is the mass of the star.
The mass of the above star cannot be calculated by a normal method. I mean, that is difficult. That was observed through the theoretical methods. That estimated method is about 9.5 to 21 M. Then we will see about the next feature that is the,
This will start rotation from the present status. After that, it will rotate backward.
The photosphere is a component of the above star. Except that there are some other components in that. Those identified components are known as the ATMOsphere. Mainly they are composed of the dust atmosphere. And there is a gas that is an existing component. That is carbon monoxide. There is a cooling region around the Betelgeuse star. That shows asymmetric features.
Now we have come to the end of the above topic. I told you some details about the above Betelgeuse star. Now you know details about the Betelgeuse star and some more about the star. I definitely think the above details would help you one day. Plus, I think you have added essential details to your knowledge library. We will meet from another so soon.
