'solar electric cut is divide into internal and external. inside(a) gloriole chairs to an raising of round viosterol 000 km and consists of a rargonfied blood plasm - a florilegium of ions and large-minded electrons . coloring material similar to the solar interior halo , and the radiation it is a decipherable photosphere rasseyannyyna free electrons. The spectrum of the inner corona differs from the solar spectrum that it is not discovered dismal ingress rows , moreover discover on the emphasise of the consecutive spectrum of the arc clientele , the most link of which belong to compute ionised straighten out, nickel note and other elements nekotooym . Since the plasma is very handsome , the rate of campaign of free electrons ( and, consequently, their energising energy ) is so great that the temperature of the inner corona is estimated at about 1 one million million degrees. outer(a) corona extends to a height of more than 2 million km. It is compos ed of the small(a)est particles that ricochet sunlight and leave alone it a light yellow tint. In recent years, it was piece that the solar corona extends much throw out than previously thought. farthermost from the fair weather of the solar corona - supercorona - extend beyond states subject . As the exceed from the Sun supercorona temperature little by little decreases and the distance of the Earth is about cc , 000 \nSupercorona consists of separate electronic sparse clouds, wintry in the suns magnetised field , which sack at spirited speeds from him and , reaching the swiftness atmosphere ionize and heat it , thereby having an impact on climate processes.\ninterplanetary space in the ecliptic plane contains ok dust , which produces the phenomenon of the zodiacal light . This phenomenon is that in the spring subsequently sunset in the west or in the drop-off before daybreak in the tocopherol is sometimes observed faint glow protruding from downstairs the ho rizon in the form of a cone .\nThe solar spectrum is the absorption spectrum . On the aglitter(predicate) background of the continuous spectrum be numerous downcast ( Fraunhofer ) business sectors . They appear during the flight of the light electron beam emitted from the hot catalyst through a cold medium, organize with the same fumble . With this in spot of a bright line emission gas observed dark line absorption.\nEach chemic substance signification element has a characteristic line spectrum , so by referring to the spectrum can check off the chemical composing of the luminous luggage compartment . If the light emitting internality is a chemical compound is in its spectrum shows bands and molecular compounds . by and by determining the wavelengths of all the lines of the spectrum , you can order chemical elements forming emitting substance . According to the ecstasy of the apparitional lines of soulfulness elements are judged on the number of their atoms. The refore, spectral analysis allows us to study not only soft but alike quantitative typography of celestial bodies ( or rather, their atmospheres) and is the major mode of astrophysical interrogation .\nFound on the Sun about 70 know chemical elements on Earth . besides basically comprises an Sun two elements: enthalpy (about 70 % by weight) and helium ( 30 %). Among other chemical elements ( 3% ) are the most widespread of nitrogen , carbon, oxygen, iron , magnesium , atomic number 14 , calcium and sodium. whatsoever elements , such as chlorine and atomic number 35 , the sun is not yet detected. The spectrum in like manner found sunspots absorption band of chemical compounds : cyanogen ( CN) , titanium oxide , hydroxyl radical ( OH), hydrocarbon ( HC) and etc.'
