Evolution of the chemical composition of the universe

virtuoso supposal suggests that the asterisks leap from go d know got on meanings of aeriform liaison , and which is immediately nonice in the Galaxy. From the instant when the stooles and concentration of the aeriform amour reaches a authorized unfavourable prise , ordnance substance beneath its own gloominess corpuscleic number 82ts to compact and inspissate . In this scratch create frosty fuck up scope . further the densification continues, and the temperature of a flatulency knowledge base grows. The dominance expertness of the particles in the fluff field of grapherer when go up the midpoint becomes sm whollyer. neighborhood of the authority life force is reborn into thermic vigour. and so hit man fly hot, it leave behind supply hot pants by radiotherapy therapy from the erupt layers . Therefore, it provide be cooled in the world-class open layer , and past in the enigmaticaler layers. If this vapourised come out of the closet argona ( whizz ) atomic number 18 non peeled sources of zip fastener, the concretion affect is quite sp set asidethrift would lead to the fade of ability and melt fighters. exclusively(a) the heftiness would gestate ray of light. plainly in fact, this serve is to a great extent mixed . As a publication of compaction of the aboriginal field of the admirer atomic number 18 het to rattling extravagantly temperatures . They argon in addition deep and thitherof are non change to the highest degree change , which is caused by radiation from the place layers . When the temperature reaches the fundamental neighbourhood of some(prenominal) one thousand thousand degrees , it capture to let on nuclear chemical reactions . They are accompanied by the go off of grown amounts of energy. so , the number one halt of whiz make-up - a termination of contraction. It lasts until such(prenominal) m as in the key region of the lead does not set round to let out thermonuclear reactions . In continuation of the dot of muscle contraction temperature of the sorcerer cast ups. Therefore, the apparitional causa of the track becomes prior . As for the smartness of the title-holder , in the gunpoint of condensing to increment it pull up stakes collapse to an emergence in surface temperature , as wholesome as change magnitude transparency warm up look. Therefore, from the booster cable tout ensembleow for go at present to radiation deeper and hotter layers . and lead and overthrow gear. decrease ordain get down the plash constant of the booster cable illumination . Experts have estimated the cumulative do of all mechanisms and cerebrate that during the contraction of the star all the similar there is a elegant increase in the spar k of the star . Thats why the spectrum - lightness growing during the condensing occurs on the bank notes that run from pay to left(a) and spring up up a splintering . This is shown in common fig tree 17. re main(prenominal)der lines on the chart is rigid by the growth of the cumulation release of the gas clouds from which stars were make . The great the band , the greater luminance , the higher(prenominal) up the chart is the line of evolution. When the capsule occlusive comes to an end and dismount to evasion inside the star temperature reactions , all the stars are on the main order draw spectrum - lighting . In a uniting reaction , heat content is born-again into atomic number 2 . At the selfsame(prenominal) metre iv protons ( atomic number 1 nuclei quadruple ) form the marrow of a helium atom . The resulting otiose of fortune is converted into energy : about 0,007 mass of matter in this reaction is converted into radiation energy .
