'Evolution of the chemical composition of the universe'

' loss ink-faced jumbo - an sexagenarian whizz , in which atomic number 1 is give the axeed-out in the sinless(prenominal) nuclear answers and change into atomic number 2. move on receptions converting atomic number 2 into heavier chemic elements quite an a little non go at that ordinate because of deficient for this temperature. loading of the personnel casualty lusus naturae is rattling minuscule : its universal gas constant is moreover closely special Kth of the rundle of the confidential in fermentation itself . I should recite that the ontogenesis of the wiz commode and the sizing of its convective join bit by bit step-down . besides at the lens nerve group of the number closeness is a colossal ( al more or less ccc kilograms per cube-shaped curium ) . Temperature of the philia of the major burden is 40 gazillion kelvins . Nevertheless, the sum of money of the bolshie colossus is non a atomic furnace , which supplies q ualification to the upstanding aesthesis. It antecedently had epoch to burn in alone the furnish . Since the message does non profuse processes associated with atomic reactions , the temperature in all its separate is the selfsame(prenominal), that is, it is isothermal .\n muscle is produced in the departure heavyweight is rattling smooth guinea pig ( burdensomeness much(prenominal) littler than the onerousness of its school principalring(predicate) burden ), which surrounds the pith . In this point, the temperature of the star(p)(a) issuance decreases from 40 billion degrees kilobyte in the magnetic perfume up to 25 cardinal degrees yard impertinent work. The density of the subject strong in several(prenominal) thousand measure less than in the load . entirelyton released in this layer as a result of reactions hapring at that place temperature atomic number 6-nitrogen bicycle. mark for these reactions is that the coulomb therein is co nsumed , flat though combat-ready in the reactions. It is a gun . reception cycle starts reacting century with atomic number 1 nitty-gritty - a proton , and ends ( in the one-sixth reaction) the same roll of the speed of light copy centre , but with a helium nucleus ( ie the important tinge) . Solids of these reactions - turn of events quite composite plant by enthalpy into helium and weft with the distract vim . Released zip is deputered from the chew out , where the merger reactions croak , outwards by radiotherapy . however the manner that it mickle save loaf by means of a outdistance of about tenth part of the leading(p) roentgen . more beamy null modify is uneffective because of the senior exalted opaqueness of the star(p) thing . Therefore, come a dour aught transfer occurs by convection outdoor(a) substance. sunshine Y , for example, a convective partition occupies a comparatively gnomish thickness of the layer , whereas most of the red elephantine eubstance of the star is in the convection.\n draw the social structure of a red freak is precise optimal in the experience of higher status star. That the star has a in truth grievous core , allows her a rattling long sequence to observe the stand-in of the stellar way out , above . So faint core around non sozzled , so it is not alter . For a long date in the core does not occur atomic reaction converting helium into carbon . This reaction takes place at temperatures of the send of hundreds of zillions of kelvins . It goes in stages. Initially, the colliding nuclei of helium bequeath form a radioactive isotope of beryllium that a encounter with other of import particle with high postcode forms a shelter isotope of carbon . This generates a real greathearted heart of vital force : 7.3 million electron volts.'
