The space inhabited by stars of different types, which differ from each other in structure, the strength of the radiation, the color, they create around them, as well as a variety of other features.Based on this individual specifications were drawn up for each type of celestial bodies.Luckily, they turned out to be too much and they can all fit in this article.Because below we look at how to identify the difference in color of stars, it generally means and how it affects the environment.
What is a star?
In fact, any star is a huge ball of hot plasma.It includes components such as hydrogen and helium, which are in contact with each other, it forms a huge flow of heat and light.After the state of these two components around normal stars, it begin to surround the planet.They are formed from the space rocks, asteroids, comets, or for other, more complex reasons.But it is worth noting that it is the difference in color of stars allows us to understand whether a particular celestial object around the planet formed.Typically, these satellites appear around stars with average illumination and heat.So what about the color of the stars are characterized by certain features that we describe below.
Heavenly bodies Class "O»
Such space objects considered to be one of the brightest in the universe.Stars blue at its greatest radius, mass, and luminosity.The name they got thanks to the fact that radiate a bluish tint that is visible at the greatest distance, even by space standards.Tom has his own explanation for the chemical - in this plasma ball elements such as helium, nitrogen, carbon and other very strongly ionized, causing ultraviolet light.Stars blue, despite its enormous size and power, live very little.On average, their existence stretches over 1 million years before the star explodes.Some of these heavenly bodies planets suitable for life in theory, form is extremely rare.A good representative of this type is a star Garnib.
little less light - category "B»
Now we consider the category of blue and white space stars that are a bit behind its predecessors in all respects.Since the name and color of stars in astronomy is always the same, we will not describe their appearance.The characteristic shade outer body receives due to the fact that the hydrogen is ionized in the plasma, while helium reaches almost neutral.This latter element creates white sheath around them, which is often presented in the form of strips.Living such luminaries for 10-15 million years, and the likelihood that they can be formed around a planet suitable for living, is very high.Find a white-blue star in the sky can be in the constellation Virgo.They called Spica.
Star category "A»
white stars are among the most popular in the cosmos.The intensity of the glow is great, but huge amounts of radiation and other radiation does not interfere with other bodies of the comic, which are located around them lead a normal life.Space objects included in this category are exclusively white color because they hydrogen reaches the maximum of the neutral state.This makes it, in the synthesis of other components, in a snow-white mass that emits countless Kelvin, is converted to heat and light.White stars also called "striped", as it emerges hydrogen on its surface in the form of strips.The duration of existence of such a star is in the range from 400 million to 2 billion years.These celestial bodies are found in us the constellation Canis Major (Sirius) and Lyra (Vega).
Star Group under the code «F»
the fact that the name and the color of the stars always coincide with each other, we are obliged to chemical processes that take place there.Because now we consider the cosmic plasma giants, which are included in the category of "white and yellow" and have a characteristic glow.Hydrogen such heavenly bodies is not contained in a large quantity as in the above cases.Here on the contrary, is dominated by other metals - iron, titanium and calcium.They are ionized, giving plasma melting slightly yellowish tint.Because the star is not too large in size, this color is for her salvation.It can be seen billions of light years because astronomers can see such cosmic objects in their telescopes, even if they are very distant from Earth.Such stars live for 4 or more billion years, and often gather around them a parade of planets where life could arise.Representatives of this group is the light of a la carte and Ropagi.
Star Called Sun ... consider the class «G»
Next on our list are yellow stars, the brightest of which is representative of our sun.These celestial bodies are filled with a variety of metals, the main of which is the calcium.They strongly ionized, so that becomes saturated yellow color.The greater the intensity of it is given other heavy metals, which also melted under huge temperatures.Strips hydrogen then quite invisible, and the very substance is contained in the yellow star in very small quantities.The lifespan of such stars is about 10 billion years.This allows not only to gather around him a certain number of planets, but also to keep them in their orbits for long enough (on space standards) period of time.For example, take a look at our solar system.
star category "K»
Since the difference in color of stars is officially recognized by the astronomical system in the world, we come to the penultimate category, which is called the "orange".As part of these celestial bodies, hydrogen is already contained in a very small state, because it manifests itself a little.White lines on the surface hardly exude, but the results of the melting of other metals, which consists of a star, are highly visible.Then there are aluminum, and titanium, and iron, and most importantly - calcium.Wherein the melting temperature of these elements here is not too high.Because of this purple ribbon cable, which can be seen in more bright stars (categories O, A et al.), There is completely absent.However, despite the low temperature performance and a small amount of orange stars can gather around him a small planetary system.They are not always born life, but they are there until until it disappears from the space itself orange "sun".His life is measured as 60 billion years.Stars-representatives of this category - Yavin, Aldebaran and Arcturus.
lowest Stars - a group of "M»
red stars are characterized by very cold temperatures and the weakening of the melting metals.They also have very little parameters in comparison with their counterparts giant, low weight and strength of light.The reddish glow around the world is not created by the fact that there is a variety of metals melted, so that the degree of oxidation reaches its maximum, and molecules are simply absorb each other.Around these red dwarfs rarely formed a planet habitable.Betelgeuse - the brightest representative of this category, whose age is estimated at tens of trillions of years.
Atypical heavenly bodies
We just looked at how to distinguish the color of the stars, but that there are certain categories of such anomalous celestial bodies are not mentioned.Well, actually there are stars in space "C" category.This is true synthesis of orange and red stars, which contains the maximum number of different metals.The main feature of the category - there are atoms that absorb the carbohydrate and hydrogen, making the star even more cold and bleak.Much more abnormal is the star of the class «S».It is very similar to the orange, but instead of a large amount of titanium in its composition includes the same amount of zirconium.
Conclusion As it turned out, about the color of the stars and how to classify them, can tell us it is their appearance.The glow and shade created thanks to the materials that are out there and melt some form mixture.They are distinguished by a specific degree, spreading into space not only light, but also the heat that can warm or burn are all nearby objects.
