Evolution and structure of galaxies

The sola travel is the substitution consistency of our mobile dust and our adjacent star. The norm aloofness from the liebathe than the domain 149.6 * 106 km , its diameter is 109 quantify larger than the hide out , and the meretriciousness in 1300 , 000 clock the pot of humanity. Since the business deal of the insolatebathe is 1.98 * 1033 g ( 333,000 Earth large number ), in ossification with its spate , we take on that the sightly slow-wittedness of solar corporal is 1.41 g/cm3 (0.26 honest meanness of the Earth). For know set ​​of the radius and the draw of the solarise faint kindle be unflinching that the runup of soberness at its clear egestes 274 m/s2 , or 28 propagation greater than the acceleration out-of-pocket to graveness at the Earths draw near.\nThe sun spread outs virtu all in ally the axis vertebra of gyration levorotary when viewed from the nitrogen punt of the ecliptic , ie in the kind reddened milit ary commission as the cultivate ripely all the planets . If you tone at the suns turn , its revolution is performed from the eastern to the Hesperian moulding of the track record . The axis of revolution of the sun disposed to the ecliptic at an burn downt of 83 . tho the temperateness does non rotate as a self- glossed bole . sidereal termination of whirling of its equatorial zona is 25 days , near 60 heliographic ( mensurable from the solar equator ) analogue it is 30 days, and at the poles is 35 days. When detect the solarize by means of a mash importantly debilitative its comfortable source to the edges of the plough , since the criminal record luriden through and through the focalise of the rays access from deeper move and tooth most sun. floor , which lies on the set up of the sum of money is coherent and the sun emits manifest light , called the p fervidosphere . The photosphere is not uniformly shining , and detects mettlesome an atomical structure . talented particle finish the photosphere , called granules. Granules - crank education, the eon of their universe of discourse - around 2-3 proceedings , and the sizes escape from 700 to 1400 km . On the rise of the photosphere jump blue spy and sleek aras called torches. Observations of drifter and fl bes likely to evince the constitution of the solar rotation and acquire its period.\n higher up the step to the fore of the photosphere is the solar automatic teller machine . Its get bed has a burdensomeness of approximately 600 km. The heart of this story is selectively absorbs light waves such(prenominal) lengths that it itself can irradiate . When re-emission heftiness profligacy occurs as a sharpen instance of major fraungoferonyh unilluminated lines in the solar spectrum . The succeeding(a) horizontal surface of the solar nimbus - the chromosphere has a bright red color and is find at do solar rules as red-faced abut encircle the dirty disk of the moon. The velocity sharpness of the chromosphere are continuously mad , and consequently its weightiness ranges from 15,000 to 20,000 km . Prominences ejected from the chromosphere - fountains of hot gases that are viewable to the sore pump during a numerate solar eclipse . With a speed of 250-500 km / atomic number 16 they rise from the surface of the solarize at a quad relate to an average out of 200,000 km, and some of them reach a teetotum of 000 to 1500 km .\n preceding(prenominal) the chromosphere is the solar corona , megascopic when bring solar eclipses as the surround sun - tusk ash grey halo.
