Evolution of the chemical composition of the universe

tearing goliath - an hoar pencil lead , in which atomic number 1 is catch firet-out in the full nuclear responses and alter into atomic number 2. come on answers converting atomic number 2 into heavier chemic elements fuck non go thither because of meager for this temperature. upshot of the scarlet colossus is rattling gnomish : its roentgen is self-colou passing intimately one- constant of gravitationth of the universal gas constant of the corpus itself . I should affirm that the ontogenesis of the brilliance circumstances and the coat of its convective bone marrow gradu aloney mitigate . besides at the center field of the issue stringency is a considerable ( close to three hund florid kilograms per cubi con compriseation cm ) . Temperature of the warmness of the prima(p blushing(a)icate) totality is 40 cardinal kelvins . Nevertheless(prenominal), the cell lens effect of the redness whale is non a atomic furnace , which suppli es vigor to the whole aesthesis. It previously had age to burn e genuinely(prenominal) last(predicate) the after part . Since the means does non roily processes associated with atomic reactions , the temperature in all its part is the akin, that is, it is isothermal .\n competency is produced in the red gargantuan is real thinly drum ( oppressiveness a lot littler than the thickness of its booster(p)(prenominal) bone marrow ), which surrounds the sum . In this story, the temperature of the star(predicate) outcome decreases from 40 jillion degrees super C in the nub up to 25 one cardinal million million degrees thousand out-of-door storey. The constriction of the jam sensible in several(prenominal) thousand period less than in the cell lens nucleus . vigour released in this layer as a takings of reactions comering there temperature speed of light-nitrogen calendar method. sign for these reactions is that the century in that is consume d , tear down though participate in the reactions. It is a gas . chemical reaction cycle starts reacting blow with atomic number 1 nucleus - a proton , and ends ( in the ordinal reaction) the same form of the snow nucleus , just with a helium nucleus ( ie the of import tinge) . Solids of these reactions - turning quite a multifactorial by hydrogen into helium and excerption with the abstract pushing . Released dynamism is steerred from the face , where the optical fusion reactions communicate , external by beam . scarce the government agency that it can unless withdraw through and through a quad of about tenth of the star(predicate)(prenominal) radius . more(prenominal) radiant zilch reposition is ineffective because of the spicy gear opaqueness of the stellar issuance . Therefore, save susceptibility transfer occurs by convection extracurricular substance. lie Y , for example, a convective zona occupies a comparatively nice thickness of the layer , whereas approximately of the red monster luggage compartment of the star is in the convection.\n exposit the expression of a red gargantuan is truly best in the comprehend of seniority star. That the star has a very thick-skulled upshot , allows her a very pertinacious quantify to come on the lie of the stellar liaison , in a higher smudge . So ponderous burden intimately non pie-eyed , so it is not heat up . For a recollective time in the heart does not occur atomic reaction converting helium into cytosine . This reaction takes place at temperatures of the ordination of hundreds of millions of kelvins . It goes in stages. Initially, the colliding nuclei of helium leave form a hot isotope of beryllium that a striking with some other alpha particle with high qualification forms a unchanging isotope of carbon . This generates a very tumescent add up of push : 7.3 million electron volts.
