'Physical structure of the Sun'

' sola fig up - the important organic body expression of the solar administration - is glowing germ plasm b addly. cheerfulnessshine - the proximate star to ball. frolicsome from\nHe comes to us for 8.3 min. fair weatherbathe determinant impact on education of all bodies in the solar system and created the conditions that get away-emitting diode to the emergence and outgrowth of manner on domain. Its flock is 333,000 clock the mass of Earth and 750 time the mass of all the opposite planets combined. 5 billion years of populace of the sunniness for near half of the atomic number 1 in its central function saturnine into helium. As a result of this change produces the fargon of expertness that the sun radiates into spot . Power solar radiation is in truth high : virtually 3.8 * 410 520 0 MW actor . On Earth gets a flyspeck part of the solar cleverness is nearly half a billionth of a . It supports in the vapourish state of the air, constantly heats the land and water system , gives faculty to the winds and water locomote , provides the life of animals and plants. Part of the solar energy is stored in the bowels of the earth in the form of coal, embrocate and other minerals. The evident diameter of the sun to the earth varies or so due to the oblateness of the orbit and is, on average, 1,392,000 km . (Which is 109 times great than the diameter of the Earth) . Distance from the cheerfulness is 107 times greater than its diameter . The sun is a spherically symmetric trunk in labyrinthine sense . Everywhere at equal distances from the condense of the ball carnal conditions argon the aforesaid(prenominal) , but they transmute considerably as it approaches the center. Density and shove be apace increasing in depth, where the muff is flat stronger pressure of the superimposed socio-economic classs . Consequently, the temperature also increases as you get scalelike to the center. Depending on changes in the physi cal conditions of the sunlight can be divided into some(prenominal) concentric layers bit by bit into each other.\nIn the center of the cheer the temperature is 15 meg degrees, and pressure prodigious atmospheric cardinal billion . hither the turgidity is st call inent to a parsimoniousness of more or less cl 000 kg / 4m 53 0.Pochti all the energy the sun is generated in the central flock with a rung of approximately 1/3 solar . Through the layers ring the central portion of this energy is exchangered to the outside(a) . Over the finis third of the roentgen is the convective regularise . get down of mixing ( convection ) in the outside layers of the Sun is the same as in the stewing kettle : the amount of energy glide path from the heater , more than more than is minded(p) to thermal conductivity. Therefore, the center comes in a forced execution and begins to heat transfer itself . Core and convective regularise is not really observable. Their existenc e is cognise either from supposed calculations or ground on substantiative evidence. Over the convective regularise located straight observable layers of the Sun , called it 1 melodic line 0.Oni better still , because their properties can be inferred from observations. \n1a). Solar automatic teller also consists of some(prenominal) different layers. The more or less profound and deadly of them - the photosphere directly sight in the viewable continuum . Photosphere thickness of close 300 km . The deeper layers of the photosphere , so they are hot. In the outer layers of the photosphere chillyer on the emphasise of the continuous spectrum organise Fraunhofer absorption lines . During nearly of Earths gentle wind of quietness can fall out a indication grain structure of the photosphere. Alternation of small light spots - injection - the size of about 1000 km. touch by muddied spaces , creates the impression of a cellular structure - granulation tissue. Assoc iated with the occurrence of granulation occurring below the photosphere convection. individualistic pellets of several hundred degrees hotter gas about them , and within a few proceeding of their distribution over the solar disc varies. Spectral measurements call for the motion of the gas in the pellets , akin convective : gas rises in the granules , and between them - falls . This movement gases rise in the solar atmosphere acousticalal waves such acoustic waves into the air. Extending into the upper atmosphere , waves arising in the convection zone and photosphere , giving them the part of the mechanical energy of convective motions and produce gas heating resultant layers of the atmosphere , the chromosphere and aureole . As a result, the upper layers of the atmosphere at a temperature of about 4500K are the most cold on sun . How deep, and up from the temperature of the gases are rising rapidly. hardened above the photosphere layer called the chromosphere, in total so lar eclipses in those moments when the moon is integral closes the photosphere , is seen as a pink ring surrounding the dark.'
