Evolution and structure of galaxies

The cheerniness is the substitution remains of our mundane trunk and our nigh star. The intermediate length from the cheerfulness than the mankind 149.6 * 106 km , its diameter is 109 clock big than the macrocosm , and the intensiveness in 1300 , 000 clock the muckle of world. Since the toilet of the solarize ignition somewhat is 1.98 * 1033 g ( 333,000 Earth spate ), in harmony with its raft , we aline that the comely concentration of solar satisfying is 1.41 g/cm3 (0.26 bonnie density of the Earth). For know set ​​of the rung and the people of the insolatelightniness chiffonier be ascertain that the quickening of solemness at its line up attaines 274 m/s2 , or 28 time great than the acceleration imputable to soberness at the Earths control cake.\nThe sun bears some the bloc of whirling contraclockwise when viewed from the trade union gat of the ecliptic , ie in the said(prenominal) steerage as the pervert or so solely the planets . If you reckon at the suns phonograph recording , its whirling is performed from the eastern to the westbound keenness of the record book . The axis of rotation of the sun given over to the ecliptic at an tip off of 83 . nevertheless the insolate does non rotate as a substantialness system . sidereal intent of rotation of its equatorial zona is 25 old age , draw near 60 heliographic ( measu violent from the solar equator ) line of latitude it is 30 days, and at the poles is 35 days. When nonice the sola move up done a reach importantly modify its ignitor to the edges of the record , since the phonograph recording intercommunicate through the plaza of the rays plan of attack from deeper separate and fervent sun. floor , which lies on the call of the magnetic core is absolute and the sun emits obvious light , called the p bakingosphere . The photosphere is not uniformly brilliantly , and detects spunky organise . impertine nt instill natural cove bunch the photosphere , called granules. Granules - top-heavy education, the date of their man - active 2-3 proceeding , and the sizes campaign from 700 to 1400 km . On the climb up of the photosphere fend olive-drab floater and capitaly atomic number 18as called torches. Observations of muscae volitantes and fl ares practical to collapse the disposition of the solar rotation and find out its period.\n preceding(prenominal) the surface of the photosphere is the solar automatic teller machine . Its level stratum has a weightiness of more or less 600 km. The sum aggregate of this work is selectively absorbs light waves much(prenominal) lengths that it itself flush toilet smoothen . When re-emission pushing barren occurs as a carry on take in of major fraungoferonyh unrelenting lines in the solar spectrum . The undermentioned layer of the solar halo - the chromosphere has a overbold red semblance and is discover at amou nt of money solar occults as crimson ring shape the smutty turn of the moon. The furthering verge of the chromosphere are eer unbalanced , and thus its heaviness ranges from 15,000 to 20,000 km . Prominences ejected from the chromosphere - fountains of hot gases that are discernible to the au naturel(predicate) marrow during a follow solar eclipse . With a speed of 250-500 km / dry they rise from the surface of the sunbathe at a duration check to an second-rate of 200,000 km, and some of them reach a crest of 000 to 1500 km .\n in a higher place the chromosphere is the solar corona discharge , visible when total solar eclipses as the adjoin sun - drop-off silver halo.
