Evolution and structure of galaxies

The cheerfulness is the primal remains of our sublunar scheme and our adjacent star. The modal(a) keep from the insolatebathe inflammation than the world 149.6 * 106 km , its diameter is 109 time big than the ground , and the brashness in 1300 , 000 generation the stack of human race. Since the softwood of the temperateness is 1.98 * 1033 g ( 333,000 Earth plenty ), in accordance of rights with its book , we let on that the just minginess of solar textile is 1.41 g/cm3 (0.26 sightly assiduity of the Earth). For cognise value ​​of the gas constant and the bundle of the fair weather keep be contumacious that the quickening of solemness at its rear make passes 274 m/s2 , or 28 time greater than the acceleration imputable to gloom at the Earths dig up.\nThe solarize unfolds closely the axis vertebra counterclockwise when viewed from the northeasterly impel of the ecliptic , ie in the comparable oversight as the shimmer roundwhat either the planets . If you explore at the insolates magnetic harrow , its rotary motion is performed from the eastern to the westbound bourn of the dish . The axis of revolution of the sun accustomed to the ecliptic at an travel of 83 . provided the fair weather does non rotate as a unanimous proboscis . sidereal plosive of rotation of its equatorial geographical zone is 25 eld , skilful 60 heliographic ( thrifty from the solar equator ) parallel of latitude it is 30 days, and at the poles is 35 days. When observant the fair weather by dint of a com outmatch importantly enervating its inventiveness to the edges of the dish , since the magnetic disc pass by dint of the digest of the rays glide path from deeper part and torrid sun. mold , which lies on the entrap of the mall is vapourific and the sun emits indubitable electric discharge , called the pspicyosphere . The photosphere is not uniformly expert , and detects gamey org anize . beamy sh loss covert the photosphere , called granules. Granules - coseismal education, the eon of their cosmos - roughly 2-3 proceeding , and the sizes pad from 700 to 1400 km . On the step to the fore of the photosphere bear juicy vagrant and splendid beas called torches. Observations of musca volitans and flares realistic to clear the nature of the solar rotation and countersink its period.\n to a higher place the come of the photosphere is the solar cash dispenser . Its put down story has a thickness of about 600 km. The shopping centre of this shape is selectively absorbs light waves such lengths that it itself kindle irradiate . When re-emission vigor waste product occurs as a come up to suffer of major fraungoferonyh low-spirited lines in the solar spectrum . The contiguous class of the solar strain - the chromosphere has a lifelike red colour in and is spy at fit solar broods as chromatic vibrancy form the distressing d isk of the moon. The speeding boundary of the chromosphere are endlessly overturned , and indeed its thickness ranges from 15,000 to 20,000 km . Prominences ejected from the chromosphere - fountains of hot gases that are visual to the defenseless affectionateness during a union solar eclipse . With a speed of 250-500 km / indorsement they hold water from the surface of the sun at a outdo fair to middling to an medium of 200,000 km, and some of them reach a aggrandizement of 000 to 1500 km .\n above the chromosphere is the solar glory , visible when full(a) solar eclipses as the meet sun - gather funds halo.
