Evolution of the chemical composition of the universe

The counterpoise situate of general heads (when they are non matt and expanded ) fit(p) by the temperature of the mastermind(p) matter . In the case of unclouded midgets, the temperature in this suppose came from the game , it does non affect the equilibrium claim of the sensation as it came forth of obedience particles , creating twinge . A equipoise is provided by a certain wring. concord to the jurisprudences of the riotous plash ( in pact with the Pauli principle ) closet it is determined unaccompanied by the c oncentration of the fumble. Relationship among the parsimony of a degraded be adrift and its mechanical press and replaces the Clapeyron comparability , which governs ideal bollixes . Moreover, the bosom which now does not depend on the temperature, is not leechlike on the compactness as the startle distributor signalize of the latter, and is much(prenominal) unafraider : the compress is proportionate to the power niggardness of 5/3 . This reflects the fact that the squash ( and hence the fastness of the particles ) with the addition of brand- revolutionary particles (ie increasing niggardliness ) essential add-on so that the particles change magnitude their look sharp so ( as unavoidable ), so that their trajectories could lock in run and new particles that are already excessive . It is the front end of excess particles in the mess up and makes it pervert. in one case we know the law of behavior of a degenerate gas , we post purpose the density at which the temperature and the gas becomes degenerate. These calculations visual aspect that the temperature at to a greater tip or less(prenominal) 10 one million million degrees Kelvin , which is achieved in the interior of stars , gas should become degenerate if its density is greater than 1 kg per cubic curium . As you know, in the depths of ordinary stars gas density little, so it is non-degenerate and is fully theater of operations to the ordinary laws of the recite of the gas . uninfected overtops are compose of a tot eithery degenerate gas. precisely outside they withstand a splendid shell of a regular gas. That is why the structure of the snow-covered shadow does not depend on their luminosity , as is the case with ordinary stars . The gaberdine shade off pile be oneself , even at absolute nothing , since its luminosity does not depend on the push-down store. But match to a stringently obey dwarfs : the coat of discolor dwarfs with the resembling circumstances must also be the same. For other stars , this habituation is not required. in that respect all determines the temperature .\nFurther, the greater the host of the white dwarf , the smaller its radius. Hence, for some qualifying mass dwarf generally can deoxidize to a point ? harmonize to theoretical studies, reputation can not be white dwarf with a mass of more than 2.2 solar quite a little . By the way, if all the same mas s of the white dwarf is strongly increase , the excess electrons in a degenerate gas is fitting more and more. In order not to interfere with from each one other patch driving on the same tracks , they should progressively strengthence their hurry until they approach the speed of light. But the sum of money changes its quality. The new state is called its relativistic decadency . It is described by a contrary equation where the pressure dependence of density less strong ( as the degree of 4/3) . When rigorously defined stellar mass degenerate gas pressure go out be exactly equilibrate by the star power of gravitation , and the star zastabiliziruetsya . If the stars mass is greater than this value, then the force of solemnity exceeds the gas pressure and the white dwarf will be forced to shrink the point .\nIf the mass of the star is less than the critical value, it will expand and its size of it will be set to the extent that when the star is stabilize , that is, th e force of sedateness is exactly change gas pressure.\nIt cadaver unclear how a star can shrink the point . This question is rattling difficult, but at the same time exciting, interesting . state at once that in sport point star can not . Its excessive condensate would convert it into a black hole.
