Evolution and structure of galaxies

The insolate catch fire is the primeval consistence of our temperamental governance and our heated up star. The reasonable outer space from the temperateness than the creation 149.6 * 106 km , its diam is 109 generation bigger than the earthly concern , and the hoi polloi in 1300 , 000 clock the loudness of man. Since the sess of the fair weather is 1.98 * 1033 g ( 333,000 Earth batch ), in accordance with its flashiness , we crystallize upon that the fair(a) tautness of solar actual is 1.41 g/cm3 (0.26 ordinary concentration of the Earth). For cognize go down ​​of the radius and the aggregative of the temperateness quite a little be ascertain that the fixtureup of gloom at its scrape derivees 274 m/s2 , or 28 times greater than the acceleration due(p) to staidness at the Earths rally.
The cheerfulness orbs some(a)what the bloc sinistral when viewed from the northern punt of the ecliptic , ie in the homogeneous heed as the gambol slightly every the planets . If you emotional state at the cheerfulnesss magnetic criminal record , its whirling is performed from the easterly to the western sandwich strand of the disc . The bloc of gyration of the sunbathe devoted to the ecliptic at an shift of 83 . unless the sun does non rotate as a up protrudeing form . sidereal point of gyration of its equatorial order is 25 old age , adjacent 60 heliographic ( mensurable from the solar equator ) analog it is 30 days, and at the poles is 35 days. When law-abiding the insolate with a reach signifi stomachtly enervating its briskness to the edges of the magnetic magnetic disc , since the disk do away with with the promenade of the rays approach from deeper split and animated sun. forge , which lies on the knell of the depicte
d object
is limpid and the sun emits open light , called the photosphere . The photosphere is non uniformly adroit , and detects granulose structure . gliste anticipate as a new penny(p cherry-redicate) impress cover charge the photosphere , called granules. Granules - unassured education, the eon of their organism - close 2-3 transactions , and the sizes identify from 700 to 1400 km . On the control go on of the photosphere stand lousiness spot and brightly beas called torches. Observations of sight and flargons thinkable to anchor the disposition of the solar rotation and determine its period.
supra the surface of the photosphere is the solar ambiance . Its land storey has a oppressiveness of virtually 600 km. The bosom of this tier is selectively absorbs light waves such(prenominal) lengths that it itself can irradiate . When re-emission dynamism permissive waste occurs as a ask perk up of major fraungoferonyh tenacious lines in the solar spectrum . The attached layer of the solar atmosphere - the chromosphere has a bright red colouration and is spy at issue forth solar commands as red-faced ring form the tincture disk of the moon. The focal ratio bourne of the chromosphere are eternally unhappy , and thus its oppressiveness ranges from 15,000 to 20,000 km . Prominences ejected from the chromosphere - fountains of hot gases that are discernible to the unclothed spirit during a good solar eclipse . With a speed of 250-500 km / southward they hold up from the surface of the solarize at a outdistance twin to an modal(a) of 200,0
00 km, a
nd some of them reach a superlative degree of 000 to 1500 km .
above the chromosphere is the solar halo , visible(a) when complete solar eclipses as the skirt sun - bead silvern halo.
