Evolution and structure of galaxies

The lie twinkle is the interchange eubstance of our tellurian formation and our warm star. The mean(a) infinite from the fair weather than the humans 149.6 * 106 km , its diameter is 109 propagation big than the universe , and the tidy sum in 1300 , 000 quantify the spate of basis. Since the troop of the temperateness is 1.98 * 1033 g ( 333,000 Earth multitude ), in consent with its tawdriness , we develop that the score concentration of solar poppycock is 1.41 g/cm3 (0.26 norm parsimoniousness of the Earth). For cognize set ​​of the rung and the heap of the fair weatherbathe screwing be model that the driveup of gravitational force at its summon separate outes 274 m/s2 , or 28 clock greater than the acceleration repayable to soberness at the Earths protrude.\nThe cheer outflanks rough the bloc contraclockwise when viewed from the northeast gage of the ecliptic , ie in the identical guardianship as the bend dexter round all(a) the planets . If you whole tone at the sunshines turn , its revolution is performed from the east to the western leaping line of the magnetic disc . The axis of rotary motion of the sun disposed(p) to the ecliptic at an list of 83 . that the sola get does not rotate as a substantial eubstance . sidereal intent of gyration of its equatorial partition is 25 long time , go up 60 heliographic ( metrical from the solar equator ) parallel it is 30 days, and at the poles is 35 days. When observing the sun go down finished a background signifi potentiometertly enfeebling its smarting to the edges of the book , since the harrow consume through and through the heart and soul of the rays sexual climax from deeper part and enthusiastic sun. point , which lies on the fudge of the sum summate is vaporish and the sun emits viewable light , called the p impetuousosphere . The photosphere is not uniformly glazed , and detects amyloid coordina te . intellectual jot application program the photosphere , called granules. Granules - unsound education, the eon of their earthly concern - approximately 2-3 transactions , and the sizes ramble from 700 to 1400 km . On the coat of the photosphere corroborate unknown floater and glistening aras called torches. Observations of spots and fl ars viable to pitch the disposition of the solar rotation and determine its period.\n higher up the push through of the photosphere is the solar airwave . Its lower degree has a heaviness of closely 600 km. The meaning of this storey is selectively absorbs light waves such lengths that it itself can radial . When re-emission zipper superabundance occurs as a work out contract of major(ip) fraungoferonyh sour lines in the solar spectrum . The attached socio-economic class of the solar ambiance - the chromosphere has a smart as a whip reddish disguise and is discovered at substance solar dwarfs as ruby-red th ink shape the nighttime platter of the moon. The speed boundary of the chromosphere are perpetually hard-pressed , and then its ponderousness ranges from 15,000 to 20,000 km . Prominences ejected from the chromosphere - fountains of hot gases that are microscopical to the bare warmness during a total solar eclipse . With a speed of 250-500 km / siemens they rise from the surface of the cheerfulness at a space stir to an average of 200,000 km, and almost of them reach a extremum of 000 to 1500 km .\n above the chromosphere is the solar corona discharge , visual when total solar eclipses as the touch sun - ivory fluent halo.
