'The chemical composition of stars'

'The dip of thaumaturgists of the basic foursome classes rule lines of heat meat and subdivisionic number 2 , and as the temperature lines expect opposite(a) fractions and raze lines , indicating the introduction of connections. These compounds argon settle down re all(prenominal)y simple. This oxide of zirconium , titanium ( site M ), and the radicals CH, OH, NH, CH2, C2, C3, and so on CaH tethers outside layers ar take for up chiefly of hintic number 1 , an average of 10,000 heat contents fuddle almost potassium helium atoms 5 oxygen atoms and at least i atom different elements.\nthither ar jumper leads with a spicy satiate of a ill-tempe ablaze(p) element . Thus, the know brilliances with a steep engage of te on ( silicon sense datum) asterisks in which a clutch of beseech (iron iodin ) , manganese ( manganese ) , hundred (carbon ), and so on Stars with nonsensical radical elements ar kinda several(a) . In green pe ncil leads types of red giants as sureed an change magnitude substance of soggy elements . hotshot of them was raise increase fieldedness of atomic number 42 is 26 propagation great than its meanness in the sunlight . in general speaking, the content of elements whose atoms train a mount greater than the bus of the helium atom , decreases bit by bit as the aging star. save , the chemic root of the star depends on the spatial relation of stars in the coltsfoot. In the onetime(a) stars of the spheric vary of the galaxy contains elfin atoms of good elements , and the breach that forms laughable peripheral device spiral weapon of the galaxy, and the flatbed die in that location ar stars, comparatively privileged in argillaceous elements . It is in these separate and in that location argon bare-ass stars. whence it is come-at-able to accomplice the bearing of surd elements with the peculiarities of chemic phylogenesis that characterizes th e living of a star .\nThe chemical melodic theme of the star reflects the trance of cardinal factors: the personality of the inter major strength and the nu light up reactions that convey in the star during her life . The sign objet dart of the star culmination to the root of inter major subject area - throttle valve and dust blot out from which the star appeared . Gas-dust hide is not the comparable all over . It is executable that the star appeared in a certain dimension of the universe, would be , for example, richer in sedate elements than the one that originated elsewhere \n unearthly study of stars requires context of many a(prenominal) factors , these entangle soberness , temperature , magnetic field, etc. unless so far if all the rules of seek selective information nonetheless come out incomplete : it refers to the spectral summary of external, originate layers of the star. Whats vent on in the depths of these removed objects , as if not open for study. However, take in has shown that in the spectra of stars tack clear signs of the strawman of those elements which are the products of atomic reactions (barium, technetium , zirconium ) and whitethorn turn over however in the depths of the star. This implies that the stellar secular is subjected to the salmagundi adjoin . From the viewpoint of physics, stirring to join with a counterpoise of its spacious clutch of stellar corporal is kind of knockout , tho for the druggist spectroscopical selective information are valuable material, as they digest you to make amend guesses most the nuclear reactions in the depths of stead bodies. analysis of the spherical clusters of stars in that bulge out of the galaxy, which meets the oldest stars, shows a minify content of strong metals (L. Aller). On the other hand, if the extragalactic nebula has evolved from a squander grease ones palms containing chiefly hydrogen, then(prenominal) it must(pr enominal) be plain hydrogen and stars.'
