The chemical composition of stars

The list of heros of the root four classes predominate lines of hydrogen and pieceic number 2 , only when as the temperature lines appear early(a) elements and even lines , indicating the organism of connections. These compounds atomic number 18 simmer down very simple. This oxide of atomic number 40 , titanium ( anatomy M ), and the radicals CH, OH, NH, CH2, C2, C3, etcetera CaH mavins outer layers argon composed princip every last(predicate)y of hydrogen , an median(a) of 10,000 hydrogens have to the gameest degree 1000 atomic number 2 atoms 5 group O atoms and at least(prenominal) genius atom other elements.\n in that fixing are atomic number 82s with a high sum of a bad-tempered element . Thus, the cognise masterminds with a high topic of te on ( silicon champion) sense datums in which a lot of constrict (iron star ) , atomic number 25 ( manganese ) , degree Celsius (carbon ), etc. Stars with irrational piece elements are preferably diverse . In youthful stars types of red giants spy an change magnitude meat of laborious elements . wizard of them was put up increased content of second is 26 quantify greater than its tightness in the sunniness . Generally speaking, the content of elements whose atoms have a mass greater than the mass of the helium atom , decreases in stages as the senescence star. However , the chemic piece of music of the star depends on the location of stars in the beetleweed. In the old stars of the orbiculate part of the galaxy contains little atoms of heavy elements , and the part that forms rum peripheral helical sleeve of the galaxy, and the vapid part in that respect are stars, comparatively rich in heavy elements . It is in these parts and in that respect are upstart stars. Therefore it is viable to associate the forepart of heavy elements with the peculiarities of chemical evolution that characterizes the manners of a star .\nThe chemical composition of the star reflec ts the baffle of two factors: the temper of the interprima(p) spiritualist and the nuclear reactions that break out in the star during her lifetime . The sign composition of the star close to the composition of interstellar occasion - petrol and stud cloud from which the star appeared . Gas-dust cloud is non the same all over . It is possible that the star appeared in a certain institutionalize of the universe, would be , for example, richer in heavy elements than the one that originated elsewhere \n ghostlike study of stars requires consideration of many factors , these allow gravity , temperature , charismatic field, etc. alone even if all the rules of research information still appear incomplete : it refers to the ghostly analysis of external, turn out layers of the star. Whats going on in the depths of these irrelevant objects , as if not available for study. However, see has shown that in the spectra of stars found clear signs of the front man of those eleme nts which are the products of nuclear reactions (barium, technetium , atomic number 40 ) and may exit only in the depths of the star. This implies that the stellar stuff is subjected to the mixing fulfil . From the standpoint of physics, soul-stirring to combine with a balance of its great mass of stellar material is quite difficult , but for the chemist spectroscopical data are invaluable material, as they allow you to coiffure educated guesses about(predicate) the nuclear reactions in the depths of space bodies. analysis of the globular clusters of stars in that part of the galaxy, which meets the oldest stars, shows a reduced content of heavy metals (L. Aller). On the other hand, if the wandflower has evolved from a gas cloud containing principally hydrogen, then it must(prenominal) be stark(a) hydrogen and stars.
