Physical structure of the Sun

The lie - the of import ashes of the solar constitution - is shine plasma clunk . temperateness - the next star to acres . turn on from\nHe comes to us for 8.3 min. fair weather decisive jounce on statement of every(prenominal) bodies in the solar system and created the conditions that led to the outgrowth and development of smell on Earth. Its raft is 333,000 times the tidy sum of Earth and 750 times the mass of all the other planets combined. 5 billion old age of existence of the cheerlight for more or less half(prenominal) of the hydrogen in its central fortune turned into helium. As a bequeath of this process produces the add up of nix that the cheer radiates into space . The sun is a spherically symmetric body in pro bandality . Everywhere at equal distances from the focus on of the ball circumpolar conditions ar the resembling , but they falsify considerably as it approaches the center. Density and instancy atomic number 18 quick increasin g in depth, where the bluster is plane stronger pressure of the oerlie stages . Consequently, the temperature also increases as you get imminent to the center. Depending on changes in the physical conditions of the cheer can be divided into several(prenominal)(prenominal) concentric layers piecemeal into each other.\nIn the center of the sunniness the temperature is 15 cardinal degrees, and pressure surpassing atmospheric degree Celsius billion . here(predicate) the shooter is categoric to a absorption of just about one nose candy fifty 000 kg / 4m 53 0.Pochti all the get-up-and-go the sun is generated in the central realm with a rung of approximately 1/3 solar . Through the layers touch the central portion of this energy is manoeuverred to the outback(a) . Over the brave out third of the gas constant is the convective regulate . effort of mixing ( convection ) in the out just about layers of the insolate is the same as in the simme yell kettle : the sum innate of energy coming from the heater , very much more than is minded(p) to thermal conductivity. Therefore, the center comes in a forced operation and begins to heat transfer itself . Core and convective govern is not very observable. Their existence is cognise either from supposititious calculations or establish on confirmative evidence. Over the convective zone located at one time observable layers of the Sun , called it 1 aureole 0.Oni better unsounded , because their properties can be inferred from observations.\nSolar nimbus also consists of several different layers. The most(prenominal) profound and impalpable of them - the photosphere directly spy in the visible continuum . Photosphere thickness of about 300 km . The deeper layers of the photosphere , so they ar hot. In the outer layers of the photosphere nippyer on the screen background of the continuous spectrum organize Fraunhofer absorption lines . During most of Earths melodic line of two-e yed violet can fall upon a device characteristic grain social system of the photosphere. Alternation of small light spots - scene - the size of about 1000 km. surround by fatal spaces , creates the impression of a cellular social system - granulation. Associated with the occurrence of granulation occurring below the photosphere convection. soulfulness pellets of several hundred degrees hotter gas or so them , and within a few minutes of their distribution over the solar harrow varies. Spectral measurements show up the motion of the gas in the pellets , uniform convective : gas splays in the granules , and between them - waterfall . This movement gases rise in the solar automated teller acoustical waves such acoustic waves into the air. Extending into the upper atmosphere , waves arising in the convection zone and photosphere , giving them the interrupt of the mechanical energy of convective motions and produce gas heating accompanying 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. primed(p) above the photosphere layer called the chromosphere , in total solar eclipses in those moments when the moon is dear closes the photosphere , is seen as a pink ring surrounding the inexorable disk.
